Hello list,

Lately I get the below error situations almost daily. I cannot see any 
particular action that causes them. They just do. Perhaps once per day. Once 
the error situation occurrs, I have to "kill -9" a number of stuck processes, 
run ctl_cyrusdb -r, and recovery. After that, I can restart cyrus-imapd, and 
it runs nicely until next time, which can be after a day or two, or only a 
few hours.

The installation is cyrus-imapd-2.2.13 on a 2.6.22.1 linux kernel.

The installation is rediculously small with only 5 users.

Neither ctl_cyrusdb nor recover, tells what errors it corrects.

What can cause the below, and what can I do to avoid it?
