Hi, just an anecdote:
Today we had to relocate our Cyrus 2.2.12 server to the other node in the failover domain for maintenance purposes. It was shut down cleanly and then restarted on the other node. The startup began with lots of messages like this one:
Mar 27 09:55:57 lvr14 master[26599]: about to exec /usr/lib/cyrus-imapd/ctl_cyrusdb Mar 27 09:55:58 lvr14 ctl_cyrusdb[26599]: DBERROR db4: Log sequence error: page LSN 5525 10229151; previous LSN 5528 3779206 Mar 27 09:55:58 lvr14 ctl_cyrusdb[26599]: DBERROR db4: Log sequence error: page LSN 5525 10229151; previous LSN 5528 3779314
...Then it seemed to start and work OK, but it got stuck as soon as the first ctl_cyrusdb was started. From then on it didn't accept any connections. I restarted the server, this time without any error messages. A little later we relocated the service back to the original node. Everything appeared fine initially, but then these familiar messages started showing up:
Mar 27 10:29:25 lvr13 pop3s[8167]: DBERROR db4: fatal region error detected; run recovery Mar 27 10:29:25 lvr13 pop3s[8167]: DBERROR: error fetching 8|3Í_^RESC^Uvüe^L^LÚO÷*û2: DB_RUNRECOVERY: Fatal error, run database recovery
...Mar 27 10:29:25 lvr13 imaps[8820]: DBERROR db4: fatal region error detected; run recovery Mar 27 10:29:25 lvr13 imaps[8820]: DBERROR: dbenv->open '/var/lib/imap/db' failed: DB_RUNRECOVERY: Fatal error, run database recovery
Mar 27 10:29:25 lvr13 imaps[8820]: DBERROR: init() on berkeleyI tried removing the databases and the environment (we have only used BerkeleyDB for deliver.db and tls_session.db anyway), but for whatever reason nothing seemed to work. Then I decided to do what I had planned for the 2.3 upgrade anyway: I moved those two databases to skiplist format (facilitated as always by Simon Matter's RPM). Now everything is fine again and will hopefully *stay* that way! Until now I had thought that the issues with BerkeleyDB were manageable, but I guess there just isn't any point.
Cheers, Sebastian Hagedorn
