OK, running Server 10.3.5 on a Dual G4 Xserve. We have run mail on it
for about 9 months with no problems. No configuration changes in the
last few weeks. Monday night directory services crashed causing a
reboot of the machine. Upon coming back up the cyrus database was
corrupted. So I figured it's just bad luck and ran the reconstruct
command (reconsturct -i) with no problems. The Mail Service came back
up and seemed to be working fine. Then the next morning at around 7 AM
the database was suddenly corrupted again, no reboot or anything this
time, and the Mail service just stopped accepting connections (POP,
IMAP or SMTP). So, I took a look at the permissions in /var/imap/db
and they were all cyrus:mail as they should be. In the logs I found a
lot (1000+) entries like this:
Oct 27 03:22:47 hal deliver[20933]: connect(/var/imap/socket/lmtp)
failed: Connection refused
Oct 27 03:22:56 hal deliver[20934]: connect(/var/imap/socket/lmtp)
failed: Connection refused
These start a few hours before the service died and get more and more
frequent until the mailboxes.db finally gets corrupted and starts
spewing errors like these:
Oct 27 07:41:43 hal mbpath[25607]: DBERROR: error exiting application:
Invalid argument
Oct 27 07:41:43 hal mbpath[25607]: DBERROR: error exiting application:
cyrusdb error
Oct 27 07:41:43 hal mbpath[25608]: DBERROR db4: operation not permitted

Oct 27 07:41:43 hal mbpath[25608]: DBERROR: opening

Oct 27 07:41:43 hal mbpath[25608]: DBERROR: opening
/var/imap/mailboxes.db: cyrusdb error
Oct 27 07:41:43 hal mbpath[25608]: DBERROR db4: Database handles open
during environment close
Another reconstruct fixed the problem temporarily, but the same thing
happened at around 7AM this morning. So, I have searched the archives
and Apple's site and still can't figure out exactly what's going on. I
have seen a bunch of people mention similar problems, but they seem to
have permissions problem when rotating the stuff in /var/imap/db, which
I don't seem to see. Can anyone give me a suggestion here? I don't
want to have to rebuild my users mailboxes every morning! ;)
