OOM erros with com.pega.pegarules.monitor.internal.pal.PALSnapshotsImpl class occupies most of heap size

Hi All,

We are facing an out of memory errors with message "java.lang.OutOfMemoryError: Java heap space".

After our heap dump analysis we found around 87% of our heap size is occupied by objects from "com.pega.pegarules.monitor.internal.pal.PALSnapshotsImpl".

System Details:

Pega Version: 8.1

Heap Size: 8 GB

WebSphere Server.

Did anyone faced similar issue? Any direction for further investigation are appreciated.

Thank you in advance.

interesting, I see similar issues for earlier version of Pega - should have been fixed since 7.3. Is this happening consistently? Any clue what use patterns you are running in particular? Also what exactly is the 8.1 patch level? I would like to see if it is happening in our internal environments?

Hi Kevin,


Yes this is frequent problem for us. We observed this more on our batch nodes. Our Pega version is 8.1.2
