Hello Ankit,

To find the root cause of an out of memory issue, you need to follow these steps:

1) If you have set the parameters in Java as per the note 1004255, then a heap dump in OOM.hprof format will be generated under .../j2ee/cluster/serverX

2) Please upload this file to MAT tool as per the note 1883568

3) A leak suspect report will be generated by the tool. Please open index.html file present in this report and you can see the objects reponsible for the memory issue

4) If you need further help, please attach the index.html file here

Regards,

Asha

Hi Ankit,

You need to adjust the java heap parameters as per your resources.

Also let us know the SPS level of java system.

Paste the default trace of the java engine
