[Dovecot] unexpected error message (maildir_sync_index)
Hello,
I recently saw these errors in my log, and one of my users complained that Dovecot disconnected him unexpectedly. Any idea what might have happened?
dovecot: Error: IMAP(bmoore@forkit.org): file maildir-sync.c: line 1075 (maildir_sync_index): assertion failed: (uid > prev_uid)

Can this be reproduced? Is there anything special in that mailbox's dovecot-uidlist file?
Do you have a core file from the crash? See http://dovecot.org/bugreport.html

Not reliably or at-will (yet); it was a bit of a surprise.
Is there anything special in that mailbox's dovecot-uidlist file?
Nothing super obvious. The UIDVALIDITY is a number that doesn't correspond to any of the files in the mailbox, but I don't know if that's typical or not.
The only thing that is, generally, unusual about the setup is that there's a cron job that periodically pulls messages out of .INBOX.Spam.Report and .INBOX.Spam.Ham, feed the messages to spamassassin, and in the case of ham, re-delivers them via procmail. The crash was very close to a 5-minute boundary (i.e. when the cron script runs).
It's probably not relevant, but another odd error that I got from this particular domain (but a different user) was this:
dovecot: Error: IMAP(xxxxxxx@yyyyyy.org): rename(/var/lib/vpopmail/domains/forkit.org/xxxxxxx/Maildir/.INBOX.Trash.wiechman.rdw, /var/lib/vpopmail/domains/forkit.org/xxxxxxx/Maildir/..DOVECOT-TRASHED) failed: Not a directory
That didn't cause a crash, but... <shrug>
Do you have a core file from the crash? See http://dovecot.org/bugreport.html
I don't; but I just modified my run files to do a ulimit -c unlimited, so that next time it *will* generate a core file.
As for the basic information:
Dovecot 1.0
Debian Linux (stable/Etch)
x86
ext3And here's my dovecot -n output:
