Hi everyone,
Last evening Cyrus died on me. Fortunately all messages were queued and nothing was lost, but I can't make sense of the error-messages. And I'd like to know, in order to ensure this doesn't happen again.
System is a SunFire V120, Solaris 9, Cyrus 2.1.10 (same one I messaged a few days ago regarding the performance problems with ctl_cyrusdb)
The "xxxx.db: Not enough space" has nothing to do with the core cyrus code, or the mailboxes.db. It's rather a problem of DB 4.x.x /cyrusdb_db3, and appears when the DB backend operates under a heavy load. (that's why this problem usually appears when the db is the choosen backend for mailboxes.db). Unfortunately It is not clear to me (yet) if this is only a DB's bug or not, but I am working on it.
If this makes you feel better take a look to the following logs. (Note that the appearing "ldapcache.db" is a non-cyrus code, that is build on DB 4.1.25-p1 and cyrusdb_db3, and is also pushing the DB backend )

From /var/log/imapd.log:

This message usually means that an underlying Berkeley DB

lmtpd[9764]: [ID 866726 local6.warning] DBERROR db4: Database handles open during environment close
What this means is you have DB handles that you have opened in a database environment and never closed, and that's not allowed when you call the enclosing DB_ENV->close method.
lmtpd[9764]: [ID 688962 local6.error] DBERROR: error exiting application: Invalid argument

master[623]: [ID 310780 local6.debug] process 9764 exited, status 75
I can't explain the error-message 'not enough space'. I have the cricket-graphs here, and the machine never lacked diskspace or memory, in fact it has never paged since it was turned on.
Any help greatly appreciated.
