Jboss eap5.0 not generating heap dump

[mayurdhande007]

Hi Everyone,

I am new to the jboss. We are using jboss  eap5 on Linux OS  and in logs we are getting "An exception or error occurred in the container during the request processing java.lang.OutOfMemoryError: Java heap space" .

we have the heap dump policy setup in java startup commands "-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=".

Kindly suggest what to check to get the heap Dump.  .

Regards,

Dhandma

There can be multiple reason for heap dump not getting generated, like threads per process is exhausted,native heap is exhausted,system has insufficient RAM and swap space. Also if java process is killed by OOM killer or not.
