Hi,
We are running Cyrus 2.2.10 on Solaris 8 using saslauthd and LDAP authentication.
Since we upgraded from Cyrus 2.1.x to Cyrus 2.2.10 it happens frequently that users inboxes get corrupted and clients cannot connect.
The entry in the logfile is:
Jan 26 12:46:13 mailsrv master[5565]: [ID 392559 local6.debug] about to exec /opt/adnmail/cyrus/bin/imapd Jan 26 12:46:13 mailsrv imap[5565]: [ID 518349 local6.debug] executed Jan 26 12:46:13 mailsrv imap[5565]: [ID 921384 local6.debug] accepted connection Jan 26 12:46:14 mailsrv imap[5565]: [ID 277583 local6.notice] login: hostname.domain.tld [192.168.5.186] kauf plaintext User logged in Jan 26 12:46:14 mailsrv imap[5565]: [ID 677757 local6.debug] seen_db: user kauf opened /var/spool/adnmail/cyrus/imap/user/k/kauf.seen Jan 26 12:46:14 mailsrv imap[5565]: [ID 736213 local6.debug] open: user kauf opened INBOX Jan 26 12:46:18 mailsrv master[26161]: [ID 970914 local6.error] process 5565 exited, signaled to death by 11 Jan 26 12:46:18 mailsrv master[26161]: [ID 621917 local6.debug] service imap pid 5565 in BUSY state: terminated abnormally
A pstack on the imapd core file gives (maybe one can get more information but I'm not a debugger guru):
root@mailsrv:~> pstack imapd-kauf-core core 'imapd-kauf-core' of 5565: imapd 0003beb8 mailbox_expunge (10ec8c, 0, 0, 118a20, 20, 538fc) + 47c 00022d74 cmd_expunge (11f800, 0, 11f800, 1ff, 10ec8c, 6e676500) + 60 0001ba18 cmdloop (11d430, a, eb800, 11d430, 108d04, 118b71) + c18 0001aa80 service_main (108c00, 1c2, 1e0, 108c00, 108c00, eb400) + 320 000190e0 main (0, 0, 1, 1, 6, 108ce8) + 924 00018438 _start (0, 0, 0, 0, 0, 0) + 108
The Cyrus IMAP server runs on a Enterprise 450, 1GB RAM, 2x300 MHz CPU with about 100 IMAP Users. Operating system is Solaris 8.
