Dump create before JBoss crashing

[codevally]

Hi All

I want to create a jboss dump file before it crash (because of JVM issues or some other). Could you please let me know how to fulfill this requirement.

Thanks.

What I know is

-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=[path-to-heapdump]

this is for OOM error.

Also you can use 'kill -3' manually.

'some other' I suppose unexpected JVM crash or system failures. There is no possibility. A hprof* file might created in case of crash.
