Concurrent Requests Remain in Pending/Standby Status

Concurrent Requests Remain in Pending/Standby Status.

fact: Oracle Application Object Library
symptom: Concurrent requests remain in pending standby status
symptom: Conflict resolution manager will not manage concurrent requests
symptom: Conflict resolution manager hangs
symptom: FND_CONFLICTS_DOMAIN table locked

cause:
A concurrent request errored out just prior to first lockup and a user terminated another job prior to the second lockup. In the first case, the FNDLIBR did not exit properly and had to be killed. In the second case, the terminated concurrent request did not exit properly and had to be killed (but its status was set to "Completed Terminated" by the standard manager which processed it).

Fix:
1. Kill the problem requests at the OS level with kill -9 command.
2. Restart the concurrent manager
