Files like __db.001 that in the folder are the bdb shared memory cache.
The log.00000001 type files are transaction logs for bdb.
If there is a problem with the bdb databases, you can sometimes fix  
the problem from the transaction log (this is what ctl_cyrusdb doees)

These are used by ctl_cyrusdb to recover (usually done when cyrus  
starts up) the bdb databases.

If you are backing up your bdb files with bd_dump then you don't need  
to worry about these files.

on a side note you can run
db_stat -m -h /var/lib/imap/db
to get information on your bdb cache performance.
