Cyrus DB Problem

[Andreas Kimpfler]

Hello,

i've got a serious problem with Cyrus Database. Since yesterday mails
will just sporadically be delivered and at some time Cyrus stops work
so no IMAP/POP3 access is possible. Also mails are hanging out in
queue of sendmail.

In the logfile i get a lots of errors which are:

pop3[14196]: DBERROR db4: PANIC: fatal region error detected; run recovery
lmtpunix[14197]: DBERROR db4: PANIC: fatal region error detected; run recovery
pop3[14196]: DBERROR: critical database situation
lmtpunix[14197]: DBERROR: critical database situation

or

and some more...

I know these errors are database related but i don't find the failure.
After a restart of cyrus imap the errors are gone for about 20
Minutes, then they'll return.
I already googled about this problem and found instructions howto
recreate database. There was told to delete everythin in db/
db.backup1/ and db.backup2/. Also delete deliver.db and
tls_sessions.db. Then check out mailboxes with ctl_mboxlist and return
them in mailboxes.db-format.
But this didn't fix my problem...

I don't know what to do further to get this handled.

I use cyrus-imapd 2.2.12 with autocreate patch on a gentoo box.
Mails are handled by sendmail with amavisd-new and sendmail to deliver
them to cyrus.
