Thank you for the reply.
Sometimes I see in maillog the following errors:
imap: SQUAT failed to open index file
imap: SQUAT failed
master: process 19488 exited, signaled to death by 11
master: service imap pid 19488 in BUSY state: terminated abnormally
Do you think that these errors are related to the lockers problem?
What will happen to the current mailboxes if I use skiplist instead of berkeley_db (for annotation_db and mboxlist_db)?
In case I continue to use berkelery_db, do you think that upgrade to db4 should help resolving the locker problem?

general consensus is to just get rid of BerkeleyDB. You can use skiplist instead. Your version of Cyrus is also very outdated. You should seriously consider an upgrade.
