[Wrapper-user] Notification for JVM Hungs

[karthik K. <kar...@gm...>]

Hi,

Reposting due to some mailing list subscription issue!!! Please ignore if
this is repeated. Inconvenience regretted..

I m facing issues like, when the JVM Hungs and restarts with below message..
sometimes, few services are not bound properly and giving us some issues..

wrapper  | JVM appears hung: Timed out waiting for signal from JVM.
wrapper  | Java Virtual Machine did not exit on request, terminated
wrapper  | Launching a JVM...
jvm 2    | Initializing...

So, i need to write a program which will be called whenever the JVM Hungs
and restarts by itself to check if the services are bound properly. for that
i need to know, from where can i invoke this program.. (Likely to call a
batch file from somewhere..).. Need to know which file and steps the Wrapper
calls to restarts the service..

Or, is there any property that can be set to send a notification by mail
when there is a JVM Hung.. I know there is a email Notification available in
prof edition. We are using a standard edition.
Can someone help me or let me know if u have done something similar to this.

Someone can throw light on why this happens.. and what could be done to
avoid such JVM Hang and restarts.

Any help in this regard will be useful
  
Thanks in Advance,

Regards,
Karthik Krishnan
