bitcoin-0.6.0rc5-linux: blkindex.dat/addr.dat: unexpected file type or format #997

I just downloaded 0.6.0rc5. When I tried to start it initially, I got the familiar "EXCEPTION: 22DbRunRecoveryException" error, so I proceeded to delete the database/ directory and the __db.* files (used the command from Issue #809). Now when I try to start it, bitcoin-qt prints out the following message:

************************

Db::open: Invalid argument       
bitcoin in Runaway exception       

terminate called after throwing an instance of 'DbException'
  what():  Db::open: Invalid argument

debug.log contains the following:

db.log says:

file unknown has LSN 300/4326497, past end of log at 1/28
Commonly caused by moving a database from one database environment
to another without clearing the database LSNs, or by removing all of
the log files from a database environment
__db_meta_setup: /home/rune/.bitcoin/addr.dat: unexpected file type or format

when I ran it before, db.log contained the same error, except it was related to blkindex.dat.

Can you try to remove/move everything from the data directory but wallet.dat?

This is what I had to do in the end. It was the only thing that worked. After the block chain has downloaded things are now working again.

There were quite big changes in the database parts of the code during the RC releases. This in combination with a hard chrash or corrupted blockchain file could have caused this. If this is working again, I guess you can close this @runeksvendsen.

I'm running into this issue. My client said something about syncing problems and either my or other clients needed an update. So I "git pull"ed, compiled. Still the same. Then I got a blockchain tar from http://eu1.bitcoincharts.com/blockchain/blockchain-2012-05-26.tar (re-downloading blockchain is not viable, takes way too long on my atom)

on second thought: maybe this is a different issue (blockchain I downloaded older db format). if so: sorry

I experienced this error as well when updating to 0.6.2. I had to download the block chain from scratch to fix it.

@molecular You will have to let the client re-download the chain or use -loadblock command to use an external file.

Closing this, please comment if you are still experiencing this with the latest version and I'll reopen.
