Yesterday our Cyrus server stopped responding and I saw the
following messages in the log file: Dec 7 18:13:55 email imaps[9684]: [ID 866726
local6.warning] DBERROR db4: PANIC: Invalid argument Dec 7 18:13:55 email imaps[9684]: [ID 864961
local6.crit] DBERROR: critical database situation Dec 7 18:13:55 email master[248]: [ID 684980
local6.warning] service imaps pid 9684 in READY state: term inated abnormally Dec 7 18:13:55 email imaps[9682]: [ID 866726
local6.warning] DBERROR db4: PANIC: fatal region error dete cted; run recovery The last 3 lines (or variations of them) were repeated over
and over. I was able to fix the server by shutting down Cyrus, running “ctl_cyrusdb
–r”, and restarting Cyrus. 1) What caused
the PANIC: Invalid argument? Is it a Cyrus bug? 2) If the
recovery had failed, I would have had to restore mailboxes.db from a
backup. We have text backups of the mailbox db created by ctl_mboxlist.
What is the proper procedure for restoring it? We would want to get rid
of the corrupt data, which would involve deleting mailboxes.db, but are there
other files that should also be deleted? Thanks, Larry |
