Under Dovecot 1.0-rc27 on Solaris 10 we noticed this error today affecting one of our users repeatedly:
Mar 28 14:02:01 myhost dovecot: IMAP(myuser): file mbox-sync-rewrite.c: line 423 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) Mar 28 14:02:01 myhost dovecot: IMAP(myuser): Raw backtrace: 0x7ac54 -> 0x42cd4 -> 0x3e968 -> 0x3f54c -> 0x3f980 -> 0x6c834 -> 0x298a0 -> 0x2114c -> 0x212e8 -> 0x22d60 -> 0x22cd8 -> 0x22ed8 -> 0x81004 -> 0x808d8 -> 0x2b3f8 -> 0x1db5c Mar 28 14:02:01 myhost dovecot: child 24818 (imap) killed with signal 6
I have no idea what the user experienced, as we simply noticed this in the logs (which appear on our consoles, too).
I hope this is enough information, as we do not run with core dumps enabled on our production servers.
