How to Increase CPM Java Heap "java/lang/OutOfMemoryError"

Hi All,

We have an r81 Management server disconnecting Console users and core dumping CPM during a policy push.

Java process consumes nearly all available core CPU%

CPM heap is 1080 (not 1024 for some reason)

 

IBM Java[18062]: JVMDUMP039I Processing dump event "systhrow", detail "java/lang/OutOfMemoryError" at 2021/07/13 11:19:12 - please wait.
IBM Java[18062]: JVMDUMP032I JVM requested System dump using '/var/log/dump/usermode/core.20210713.111912.18062.0001.dmp' in response to an event

Reviewing SKs  sk171173 says to raise it with TAC and they will make the change.

First response is a SK for SmartView crashing not CPM so no help there...

 

Does anyone know how to increase the Heap for CPM to stabilize this server? 

 

Regards,
