Applies to:Oracle Communications Messaging Server - Version 6.0 and later
Information in this document applies to any platform.
IMAP response time degrades, imapd threads build up, pstack shows threads waiting for locks in the DB, processes like mboxutil or reconstruct hang, and imcheck -s shows the process holding the lock iss a PID that no longer exists.
You might also see DB transaction log files accumulating.
If autorestart is enabled, once all the imapd threads are hung, msprobe would detect IMAP being unresponsive and call for restart of all the store processes, that would clear the problem, but is a non-optimal way to clear it.
The customer had recently restarted only the imapd processes rather than a full restart of Messaging Server.
