Troubleshooting
Problem
During migration to or from WebSphere Application Server with WebSphere Extended Deployment, WebSphere Virtual Enterprise, or Intelligent Management cells, the system logged repeated ARFM4998W warning messages in the new deployment manager's SystemOut.log file. These messages do not affect your environment, and no action is required.
Symptom
Repeated warning messages such as the following example appear in the log file:
[9/6/13 14:57:08:549 EDT] 00000053 AllocSequence W ARFM4998W: Something suspicious happened in ARFM; data is <null>, and the exception (if any) is java.lang.Exception: Noted conflicting deallocation to insts=442.0, power=6350.0977, desiredInsts=224.0, desPLo=6285.282, desPHi=6412.899

Cause
The system logs these messages when there are temporarily two ARFM controllers running simultaneously during migration. After you fully migrate all nodes, these messages should not be logged.
Environment
This error affects WebSphere Application Server with the following features enabled:
- WebSphere Application Server Version 8.5 or later with Intelligent Management cells
- WebSphere Virtual Enterprise Version 7
- WebSphere Extended Deployment Version 7.0 and 6.1
