I finally succeeded in starting it again. I kill -9'd the ctl_cyrusdb process. On shutdown it wrote this in the syslog: Nov 15 22:30:20 doohan cyrus/master[12843]: process 12844 exited, signaled to death by 9 Nov 15 22:30:21 doohan cyrus/master[12980]: about to exec /usr/sbin/ctl_deliver Nov 15 22:30:21 doohan cyrus/ctl_deliver[12980]: duplicate_prune: pruning back 3 days Nov 15 22:30:21 doohan cyrus/ctl_deliver[12980]: duplicate_prune: purged 0 out of 56 entries Nov 15 22:30:21 doohan cyrus/master[12981]: about to exec /usr/sbin/tls_prune Nov 15 22:30:21 doohan cyrus/tls_prune[12981]: mydelete: starting txn 2147483653 Nov 15 22:30:21 doohan cyrus/tls_prune[12981]: mydelete: committing txn 2147483653 Nov 15 22:30:21 doohan cyrus/tls_prune[12981]: mydelete: starting txn 2147483654 Nov 15 22:30:21 doohan cyrus/tls_prune[12981]: mydelete: committing txn 2147483654 Nov 15 22:30:21 doohan cyrus/tls_prune[12981]: tls_prune: purged 2 out of 2 entries Nov 15 22:30:21 doohan cyrus/master[12843]: WARNING: cannot find executable for service 'pop3' -- ignored Nov 15 22:30:21 doohan cyrus/master[12843]: ready for work Nov 15 22:30:21 doohan cyrus/master[12982]: about to exec /usr/sbin/ctl_cyrusdb Nov 15 22:30:21 doohan cyrus/ctl_cyrusdb[12982]: checkpointing cyrus databases Nov 15 22:30:21 doohan cyrus/master[12983]: about to exec /usr/lib/cyrus/bin/notifyd Nov 15 22:30:22 doohan cyrus/notify[12983]: executed Nov 15 22:30:22 doohan cyrus/ctl_cyrusdb[12982]: archiving log file: /var/lib/cyrus/db/log.0000000006 Nov 15 22:30:27 doohan cyrus/ctl_cyrusdb[12982]: archiving database file: /var/lib/cyrus/mailboxes.db Nov 15 22:30:27 doohan cyrus/ctl_cyrusdb[12982]: done checkpointing cyrus databases Nov 15 22:30:27 doohan cyrus/master[12843]: process 12982 exited, status 0 I then did an /etc/init.d/cyrus21 stop for good measures, and got the following in syslog: Nov 15 22:31:40 doohan cyrus/master[12843]: exiting on SIGTERM/SIGINT Nov 15 22:31:40 doohan cyrus/notifyd[12983]: got SIGTERM/SIGINT, trying to exit cleanly...

So I tried connecting to the imap server and it worked. So now it runs... but I have no idea what kept it from running and what made it run again... and worry about whether it will happen again...:-) - Steinar ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
