Oracle Ebusiness Suite 22.214.171.124, 126.96.36.199 on Solaris 9 64-bit. One of the workflow agent processes occassionally hangs. V$session_wait shows state = 'WAITING', event = 'buffer busy waits' and seconds_in_wait keep incrementing until I resolve it by flushing the buffer cache. Since the session holds multiple locks on key application tables, almost all the sessions hang waiting on "enqueue". I tracked down the block to AQ$_WF_JAVA_DEFERRED_I table. Has anyone seen anything similar? Any ideas on how I can debug it further? I've seen performance issues with the AQ tables before and am thinking of rebuilding the queues and reorganizing the objects. Hopefully this will alleviate the problem.
