12/03/30 10:12:55 [libopmnoc4j] Port information in the ONS notification is incorrect for proc: 311. Some of the reasons for the failure are:
1. ajp, rmi and jms ports could not be bound by the process.
2. If a port value for a certain port ID is handed by OPMN to the OC4J process and this value is not returned back in the ONS notifications. For example, this can happen for certain bad JGroups related configurations.

Expected Behavior
Expect behavior is that the processes should start without a hitch

The issue can be reproduced at will with the following steps:
1. Increase the number of processes in the context.xml file
2. Try to start the processes

The issue has the following business impact:
Due to this issue, users cannot start oacore processes.
