What happened to my db/ ?

[Nick Fisher]

Hello All,
  I recently moved my cyrus-imapd install from one machine to annother.
The move went *quite* well, I had both servers stoped and rsynced the
live server's data (/var/imap, /var/spool/imap) over to the new server.

Everything was fine untill I started playing with SSL, at that point I
started having problems getting cyrus running after a restart.

Here is what I was seeing in my logs:
"""
Jan  8 17:27:11 [tls_prune] DBERROR db4: operation not permitted during
recovery.
Jan  8 17:27:11 [tls_prune] DBERROR: opening /var/imap/tls_sessions.db:
Invalid argument
Jan  8 17:27:11 [tls_prune] DBERROR: opening /var/imap/tls_sessions.db:
cyrusdb error
"""

Somewhere I found a post from someone having the same problem. They said
that they could get cyrus working again by removing all the files in
/var/imap/db. So I did that. Now I can start cyrus and read my mail
*PHEW*. However I now have a new raft of errors showing up in syslog.
Everytime I start cyrus I get this:

I don't *think* it's a permissions problem...

I'm using EXT3 so I don't think it's anything to do with the "chattr +S"
stuff.

I tryed recompiling cyrus.... it didn't help.

The idea of cyrus dying fills me with dread. Someone please help me out
here.... what is going on and how do I stop it? If someone can give me a
bit of a shove in the right direction it would be MOST helpfull.....
links... generall information.... even mild abuse, all gratefully
accepted.

Many thanks....
