Title: client won't start
Post by: flaxceed on December 31, 2011, 05:06:54 AM
I can't get my client to load- it just gives me errors.  My debug log says:

EXCEPTION: 22DbRunRecoveryException       
DbEnv::open: DB_RUNRECOVERY: Fatal error, run database recovery       
C:\Program Files\Bitcoin\bitcoin.exe in AppInit()       

and

EXCEPTION: 11DbException       
Dbc::get: Bad address       
C:\Program Files\Bitcoin\bitcoin-qt.exe in Runaway exception       

and

EXCEPTION: 11DbException       
Dbc::get: Bad address       
C:\Documents and Settings\netbook\Desktop\bitcoin-0.5.1-win32\bitcoin-qt.exe in Runaway exception       


Can anyone clue me in to what is going on?  It happened out of the blue.

Your wallet is corrupt

Thank you tt.  Can you suggest a good next step?

I have never done this but restarting bitcoin-qt using the --rescan option is supposed to repair the db.

-or-
I have done this:
1. Make sure you have a backup of the wallet.dat
2. delete all files except wallet.dat from the APPDATA\bitcoin directory (not using windows, but I think you should be able to find it)
3. start bitcoin-qt.exe then wait for the block chain to download..a few hours if I recall correctly

Hey Fred- I did as you said (using %APPDATA%\Bitcoin to see the folder contents) but do I also delete the database folder?  It looks like there are just two log files there.  Thanks a million for your help!

OK I just ignored the database folder and put the old wallet back in and started the client and it worked perfectly and is now synchronizing with the network.  Thanks a bunch guys I appreciate your willingness to help!

I wasn't sure, hence the alternative method, the one I knew would work.

Sure, you could have deleted the database folder.

Just remember to always preserve the wallet.dat.  If you lose that, you will lose your bitcoins from that wallet.

Glad everything worked out.
