PK01814: HEAP VALUES RETURNED FROM PMI ARE INCORRECT AFTER SERVANT REGIONIS RECYCLED.

APAR status
Closed as program error.

Error description
The application receives freeMemory, totalMemory and usedMemory
data by using PMI. Usually, these data have correct values.
However, when a servant region was restarted (by cancel
command), the Heap values returned from PMI are incorrect.
  Further diagnosis confirms that when a servant is terminated,
the PMI data for the terminated servant is retained. In the case
of freeMemory, totalMemory and usedMemory (as well as,
numThreadsStarted and numThreadsDead) this information is
misleading because it gets aggregated in with the values for
active servants.

Note: this problem does not occur if all CR and SRs are recycled

****************************************************************
The PMI values for freeMemory, totalMemory and usedMemory
(within jvmRuntimeModule) are incorrect after a servant
terminates. The values for the terminated servant are being
included in the aggregated totals.
Problem conclusion
PMI was modified to not include the values for terminated
servants when aggregating the freeMemory, totalMemory and
usedMemory values.
