Folks, We are continuing our quest to upgrade our Cyrus IMAP servers from RHEL 3 i386 with Cyrus version 2.2.12 to RHEL 5 x86_64 machines running cyrus version 2.3.14. I've had 2 cases now where the upgrade appeared to go smoothly. Cyrus comes up, logs look fine, lmtp mail is flowing in, users are happy, and the logs are perfect. For a few minutes until the alians corrupt the database. Suddenly we see stuff like: Dec 5 15:02:55 xxxxxx lmtp[4724]: DBERROR: error fetching <9311515.102504011260020246443.JavaMail.em-build@xxxxxxxxxxxxxxxxxxxxxxx>: DB_PAGE_NOTFOUND: Requested page not found Dec 5 15:02:55 xxxxxxxxx lmtp[4724]: DBERROR: mystore: error storing <9311515.102504011260020246443.JavaMail.em-build@xxxxxxxxxxxxxxxxxxxxxxx>: DB_PAGE_NOTFOUND: Requested page not found Dec 5 15:03:55 xxxxxx lmtp[4724]: DBERROR db4: page 0: illegal page type or format Dec 5 15:03:55 xxxxxx lmtp[4724]: DBERROR db4: PANIC: Invalid argument Dec 5 15:03:55 xxxxxx lmtp[4724]: DBERROR: critical database situation It goes downhill from there. LMTP doesn't deliever, the IMAP port stops responding. DBERRORs scroll. I could not dump the mailboxes.db with su cyrus -c "/local/cyrus/sbin/ctl_mboxlist -d -f /imap/conf/mailboxes.db" > /tmp/mailboxes.corrupt Just more errors. I could not move mailboxes.db out of the way and load a known good dump back in its place....more dberrors. Finally, I moved the db/ directory and created an empty db/ as well as moved the deliever.db out of the way (some lmtp errors were citing that file.) I turned her back on and she's now up and running like nothing happened. Can someone help me understand what happened here and how to avoid it?
