Found an imap crash. I'm using the CVS copy from March 23. This is
running under Linux, kernel 2.6.11.something. We use mbox over NFS,
everything is on the NFS server. There is currently only one dovecot
server accessing the mailbox.
Here's the log messages:
dovecot: Apr 05 13:11:20 Error: 27911 IMAP(support): UIDVALIDITY changed
(1112720886 -> 1112721068) in mbox file /mailhome/new/m/support/mbox
dovecot: Apr 05 13:11:20 Error: 27911 IMAP(support): mbox sync: UID inserted in
the middle of mailbox /mailhome/new/m/support/mbox (316790 > 316789)
dovecot: Apr 05 13:11:20 Error: 27911 IMAP(support): Corrupted index cache file
/mailhome/new/m/support/.imap/INBOX/dovecot.index.cache: indexid changed
dovecot: Apr 05 13:11:20 Error: child 27911 (imap) killed with signal 11
Here's a backtrace. Note that cache->hdr is NULL.
