After I read your message again, you should _not_ kill an imapd process by hand. This is probably a large part of your problem. If you want to be able to do this, you need to upgrade to cyrus 2.2.3. > > > Is there a fix/solution for the SSL imap/pop daemons dieing other than to > > > upgrade t

Your drives are working overtime. There is nothing waiting to be written (good), but service time is high and I imagine things feels a bit sluggish. Is this software RAID? Can you add more drives? I do not know if skiplist will reduce your disk load (my guess is yes because skiplist does not m
