Timo,
A rare assert and core dump out of 1.0alpha3. My setup:
Solaris 9, mbox format, using imap only. Built dovecot
with gcc 4.0.1. The syslog for this was:
Oct 14 11:57:56 emerald dovecot: [ID 107833 mail.info] imap-login: Login: user=<epmccull>, method=PLAIN, rip=137.146.210.59, lip=137.146.210.52, TLS
Oct 14 11:58:56 emerald dovecot: [ID 107833 mail.info] imap-login: Login: user=<epmccull>, method=PLAIN, rip=137.146.210.59, lip=137.146.210.52, TLS
Oct 14 11:59:03 emerald dovecot: [ID 107833 mail.error] imap(epmccull): Corrupted index cache file /home/students/e/epmccull/.imap/INBOX/dovecot.index.cache: invalid record size
Oct 14 11:59:38 emerald dovecot: [ID 107833 mail.error] imap(epmccull): Corrupted index cache file /home/students/e/epmccull/.imap/INBOX/dovecot.index.cache: Cache record offset 1768 points outside file
Oct 14 11:59:39 emerald dovecot: [ID 107833 mail.error] imap(epmccull): Corrupted index cache file /home/students/e/epmccull/.imap/INBOX/dovecot.index.cache: used_file_size too small
Oct 14 11:59:39 emerald dovecot: [ID 107833 mail.error] imap(epmccull): file mbox-lock.c: line 518 (mbox_lock): assertion failed: (lock_type == F_RDLCK || mbox->mbox_lock_type != F_RDLCK)
Attached is a gdb session on the core dump. Thanks.
