It appears when the main window shows "Loading wallet...". Long version: I built the executables from the latest source code from bitcoin GitHub repository. I had to use "--disable-wallet" because of Berkeley DB version issue and "--with-incompatible-bdb" didn't work. (There were all sorts of errors. I googled a lot and every attempt reached a dead-end. "--disable-wallet" failed at the beginning, but somehow it became working lately.) The generated bitcoin-qt.exe ran OK. It's of version 0.14.99.blah.blah. It stuck on "Load block index..." and never moved on. (Not sure if it's normal.) Then there was an internet glitch. The network was down. The program crashed. After that, no version of the executable could run without crashes. Is it that the blockchain data is corrupted? Is there a way to fix it?
Trying to salvage some coins from 2013. Core (bitcoin-qt.exe v0.8.1-beta on Windows 8.1) is taking weeks to DL the blockchain as expected but keeps crashing now. Can I upgrade to a newer version without losing what I've gotten already (about 75% complete)?
Currently there are 134305 blocks remaining. When I start it up it works pretty smoothly for a while but then slows down. I leave it running while I'm gone but the last several days when I've come back it has crashed and gives me an I/O error, and I have to hit OK then start it back up. It does appear to be further along when I start it back up but not by a whole lot. So this has really slowed my progress. It's reindexed about 75% though, and so I don't want to start over from the beginning. The drive it is on has ~400gb of free space so that's not the issue. I have 8gb of memory, and the task manager says bitcoin is taking up about 500mb, but it's using 60-85% of my cpu at a time. If I download a newer version of core, I can just copy/paste the old wallet.dat file, right? But wouldn't it have to start downloading the entire blockchain again from the beginning? If so, is there any quicker method? While typing this, it crashed twice. It only runs for about 10 minutes. The version I have doesn't have any settings I can change. I read that there's a db size limit you can change in later versions that could help. This one does have a "debug window" with a command line console but I don't really know what to do with it. Here is a list of available commands: ￼

A few years back I bought a bitcoin, when they were at peak value pretty much. I paid about a thousand dollars for the coin, shortly after the value crashed and I tried to forget the whole thing. Now the value is coming back, and so I wanted to check up on my coin, I opened bitcoin-qt.exe and my coin is nowhere to be found, I know it is on my PC somewhere, but I don't remember the information - I do remember the password, but I don't know what name I would search for on my disk to find and open the wallet. The app is still downloading its 76 weeks behind now, but it is also telling me it is out of date, I don't want to update the app before I find my wallet. Since I bought the coin, I have installed two new hard disks, when I bought it my disk F: was my disk C: so could the program be checking C: for a wallet, but my wallet is hiding in the F: disk somewhere? I did open the bitcoin app from the drive on F: TLDR: Bought a bitcoin a few years back, forgot where I saved it, can remember the password I created for the wallet, but not the wallet name, or number or any ID. How would I go about finding and recovering the coin?

Setting up solo mining just targeting USB erupters? PC/Mac?
I am having trouble trying to get solo mining started on either my PC or Mac. I have a PC set up that is using three 7950s that are mining Litecoins. I'd like to have my 2 USB erupters solo mining Bitcoins for fun on the same system. I have the drivers installed for the USB miners and my system recognizes them. I am starting Bitcoin-QT as -server My bitcoin.conf looks like this: listen=1 server=1 rpcuser=user rpcpassword=pass I set up a BFG .bat like this: bfgminer.exe -o 127.0.0.1:8332 -O -u user -p pass When I launch that, BFG just crashes. I have also tried it with CGminer and that crashes also. I'd like to keep CGminer on the cards Litecoin mining and use BFG for the USB miners. How do I get BFG to work just with the USBs? Also, do I need to input a Bitcoin address somewhere so if I did solve something I get the payout? Sometimes, I do more work on my Mac and am also trying to set up the USBs to mine on a Mac using Diablo miner. Will that work the same way as the PC setup once we get it figured out? Thanks for any help.
Hi guys, I'm fairly new to Bitcoins and I'm already scared that I've lost my wallet. I used bitcoin-qt.exe to create a new one, let it sync, then transferred some funds over to it. Since then, every time I try to run it, it just crashes instantly. I'm running Windows 8.1 and neither the 32-bit nor 64-bit versions of bitcoin-qt work at all. If I debug with Visual Studio 2012: it displays the following error:
Unhandled exception at 0x00B906CA in bitcoin-qt.exe: 0xC0000005: Access violation reading location 0x00000004.
I tried using Bitcoin Armory and that won't work either. Is there any alternative Bitcoin client or some method I can use to recover my wallet and its bitcoins? I am desperate for help. Thank you so much. Edit: Apparently version 0.9.3 works fine. I'm going to see if I can recover my wallet with this version. Edit: I uninstalled absolutely everything related to Bitcoin, deleted everything except my wallet, torrented bootstrap.dat, installed Bitcoin 0.10.0, and it works now, but it won't seem to recognize my wallet backup, even running with -rescan. I'll try some more. Thanks for the help though, you guys.
Hi All, Running Windows 8 64-bit, Armory v0.9.32-beta-85959b20d8, Core Bitcoin v0.10.2. Armory loads up just fine, and using Process Explorer (Sysinternals tool), I am able to see ArmoryQT.exe as the parent thread with bitcoind.exe as one child thread (which has a conhost.exe child thread) and another child thread for guardian.exe (which also has a conhost.exe child thread) This is how it looks:
Now, as soon as I load Armory, the wallet consistency check passes and then it's stuck in "Initializing Bitcoin Engine" with no progress at all (just the rotating grey/green wheel) - then about 15 minutes later, I'll notice that the bitcoind.exe process and its child disappear. Guardian.exe is still running though. Now, when I disabled Armory from controlling bitcoin, I can load Bitcoin-Qt.exe no problems, it syncs with the blockchain no issues, and Armory will phase in and out of being connected. Which is totally weird....like the rpc connection somehow gets lost and reconnects at random times. But, even when Armory shows it's connected, and Bitcoin-Qt.exe shows that's it's fully synced with the blockchain, it doesn't update any transaction info in Armory at all. Now, I can see in the blockchain that my last few transactions already have 38 confirmations, but Armory still shows that there are 0 confirmations and that the transaction hasn't hit the blockchain yet. Obviously this isn't true. So, I turn to y'all for some help and guidance....I've scoured their forums, and I've tried all the suggestions, so I'm turning now to the trusted reddit community for some insight and help. Any ideas?! I mean, I could probably just backup my wallet, uninstall both armory and bitcoin, then do a clean install, then wait a month for the blockchain to sync, but I'd prefer to have to avoid this if that's AT ALL possible. Also, not sure if this is relevant, but even though the blockchain is synced, shortly before bitcoind.exe goes out of commission (only when run through Armory, bitcoin never crashes when loaded separately) the cpu % for that process spikes to about 45-70% for a few minutes, which sounds like it's processing headers and what not, and then just poops out. I have a quad-core AMD A6-3600 - not the BEST but not the worst either.... Ok, help....please.... EDIT: formatting
I've installed the client and it works great, until I exit the program. Upon restart, it crashes immediately, giving me the following error: "Runaway Exception" A fatal error occurred. Bitcoin can no longer continue safely and will quit. EXCEPTION: N5boost12interprocess22interprocess_exceptionEAccess is denied. C:\Program Files\Ziftrcoin\ziftrcoin-qt.exe in Runaway exception Windows 8.1 64 bit, FYI. I've tried reinstalling, changing the read-only flag, and reinstalling to a different location, all with no luck. I always get this message by the second time i run the program. Any suggestions?
Bitcoind.exe has stopped working when I start Armory.
I wanted to try out Armory, since it supposed to be super secure and all. Installed it, took all the security steps, made and test the back-up. Now when I start Armory, windows immediatly reports Bitcoind.exe has stopped working. Armory will stay offline. I have already pointed Armory to my correct Blockchain data and Bitcoin QT folder, since I dont save them in the default location. Also skipping the online check does not make any difference. When rebooting my computer, sometimes Armory will sync for a few minutes and then Bitcoind.exe crashes and armory goes back to Offline :\ Anyone know what I can try to make this work ? Thanks
guys my bitcoin wallet suddenly appears with this error. Error loading block database.

I mined this last year with 2 computers over at least a month. How do I get the bitcoin value I earned?
http://eligius.st/~wizkid057/newstats/userstats.php/17td8F8PXVnBboTVRtq4Er3LYQj92sS9Le I mined this last year with 2 computers over at least a month. Along with this stats page, I used the bitcoin-qt software in Windows to check my balance. I had 0.3 bitcoins due to 2 payouts from Eligius' pool. Now, after not having looked at this for over a year, I tried loading bitcoin-qt.exe and it crashed when trying to update my wallet and it said I have 0.00 BTC. I updated that program and now it shows a different address. How do I get my money back?
BitcoinQT keeps failing to download the blockchain in new ways.
I bought a bitcoin early last year and used bitcoinQT just fine. Then a few months ago I rebuilt my computer and added an SSD, so I backed up the wallet and reformated. Since I didn't plan to sell anytime soon I didn't really need to reinstall right away. A few weeks ago I decided to reinstall QT, but I would need to have the chain on the HDD to preserve space. I used the -datadir parameter and got 9gb into the chain before it stopped downloading blocks and showed a banner in the program that said "Warning: Displayed transactions may not be correct! You may need to upgrade, or other nodes may need to upgrade." This was with version 0.8.5. The holidays came and I got side tracked until now. I got back to it and the problem was still there, but I saw 0.8.6 was out, so I deleted the chain and started over. Now I've gotten 10gb into the block and suddenly while downloading QT crashed with a message "System error:database corrupted." I opened QT again and it went back to work and got another 1 hour into the download before it happened again and now when I try to open the program it errors every time with this message. Though sometimes when I double click the shortcut, rather than crashing with this error it will open but ignore the -datadir, starting to download the chain from the beginning and putting it in my user folder on the SSD. Any ideas? Thanks The directories Im using are C:\Program Files (x86)\BitcoinQT for the program and G:\Programs\Bitcoin\QT-Files for the blockchain The target Im using in the shortcut is: "C:\Program Files (x86)\BitcoinQT\bitcoin-qt.exe" -datadir=G:\Programs\Bitcoin\QT-Files\Bitcoin
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), uninstall all earlier versions of Bitcoin, then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux). If you are upgrading from version 0.7.2 or earlier, the first time you run 0.9.0 your blockchain files will be re-indexed, which will take anywhere from 30 minutes to several hours, depending on the speed of your machine. On Windows, do not forget to uninstall all earlier versions of the Bitcoin client first, especially if you are switching to the 64-bit version.
Windows 64-bit installer
New in 0.9.0 is the Windows 64-bit version of the client. There have been frequent reports of users running out of virtual memory on 32-bit systems during the initial sync. Because of this it is recommended to install the 64-bit version if your system supports it. NOTE: Release candidate 2 Windows binaries are not code-signed; use PGP and the SHA256SUMS.asc file to make sure your binaries are correct. In the final 0.9.0 release, Windows setup.exe binaries will be code-signed.
The 'chainstate' for this release is not always compatible with previous releases, so if you run 0.9 and then decide to switch back to a 0.8.x release you might get a blockchain validation error when starting the old release (due to 'pruned outputs' being omitted from the index of unspent transaction outputs). Running the old release with the -reindex option will rebuild the chainstate data structures and correct the problem. Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan the blockchain for missing spent coins, which will take a long time (tens of minutes on a typical machine).
Rebranding to Bitcoin Core
To reduce confusion between Bitcoin-the-network and Bitcoin-the-software we have renamed the reference client to Bitcoin Core.
Autotools build system
For 0.9.0 we switched to an autotools-based build system instead of individual (q)makefiles. Using the standard "./autogen.sh; ./configure; make" to build Bitcoin-Qt and bitcoind makes it easier for experienced open source developers to contribute to the project. Be sure to check doc/build-*.md for your platform before building from source.
Another change in the 0.9 release is moving away from the bitcoind executable functioning both as a server and as a RPC client. The RPC client functionality ("tell the running bitcoin daemon to do THIS") was split into a separate executable, 'bitcoin-cli'. The RPC client code will eventually be removed from bitcoind, but will be kept for backwards compatibility for a release or two.
The behavior of the walletpassphrase RPC when the wallet is already unlocked has changed between 0.8 and 0.9. The 0.8 behavior of walletpassphrase is to fail when the wallet is already unlocked:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 Error: Wallet is already unlocked (old unlock time stays)
The new behavior of walletpassphrase is to set a new unlock time overriding the old one:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 walletunlocktime = now + 10 (overriding the old unlock time)
Transaction malleability-related fixes
This release contains a few fixes for transaction ID (TXID) malleability issues:
-nospendzeroconfchange command-line option, to avoid spending zero-confirmation change
IsStandard() transaction rules tightened to prevent relaying and mining of mutated transactions
Additional information in listtransactions/gettransaction output to report wallet transactions that conflict with each other because they spend the same outputs.
Bug fixes to the getbalance/listaccounts RPC commands, which would report incorrect balances for double-spent (or mutated) transactions.
New option: -zapwallettxes to rebuild the wallet's transaction information
This release drops the default fee required to relay transactions across the network and for miners to consider the transaction in their blocks to 0.01mBTC per kilobyte. Note that getting a transaction relayed across the network does NOT guarantee that the transaction will be accepted by a miner; by default, miners fill their blocks with 50 kilobytes of high-priority transactions, and then with 700 kilobytes of the highest-fee-per-kilobyte transactions. The minimum relay/mining fee-per-kilobyte may be changed with the minrelaytxfee option. Note that previous releases incorrectly used the mintxfee setting to determine which low-priority transactions should be considered for inclusion in blocks. The wallet code still uses a default fee for low-priority transactions of 0.1mBTC per kilobyte. During periods of heavy transaction volume, even this fee may not be enough to get transactions confirmed quickly; the mintxfee option may be used to override the default.
