Nishant,

Mailing the list is fine: there's no need to mail me separately.

Does the JVM and/or Tomcat actually crash? That's an important
difference: if Tomcat simply stops responding to requests, that's likely
to be a different problem than an actual crash.

Eh... okay, if you say so.

No.

I'm not sure what you mean, here.

The screenshot indicates that you have 756MiB free of a 1016MiB heap.
That looks good to me. It also indicates that your "jvehelp" servlet
seems to be taking forever to do its work. Perhaps you should take a
thread dump and figure out what your servlet is doing when it stalls?

Only one thread is in the "keepalive wait" state, and it has been there
for 6.5 seconds. What is your keepalive timeout? Is it set to an
appropriate amount?
