E-WL: E-PN: WebLogic Memory Increasing Excessively if Push Notification is Enabled (Doc ID 2991921.1)

Last updated on DECEMBER 08, 2023

Applies to:

PeopleSoft Enterprise PT PeopleTools - Version 8.60 and later
Information in this document applies to any platform.

Symptoms

Upgraded to PeopleTools 8.60 and using Push Notification. Noticing that WebLogic is consuming a lot of memory which exceeds way above the heap size. To investigate further, we captured a memory dump as follows:

 

/*********************************************************************************************/

1. Run the following command

<JAVA_HOME>\bin\jcmd <pid> Thread.print > jcmdnew.log

where <pid> is the PID of the PIA Java process.

2. Upload the jcmdnew.log to the service request.

3. Run the command below from an admin command prompt:
tasklist /v txt > tasksnew.txt

4. Upload the tasksnew.txt file to the service request.

/**********************************************************************************************/

 

Looking at the generated tasksnew.txt file, we see the following error, over and over:

 

/**********************************************************************************************/
