Jboss server is not responding after some time.

Hi

 

We are running one web application on jboss-4.0.3 server and after bringing up the server for some time the server is up and running successfully but suddenly the requests are not reaching the particular application We are accessing the application using the web browser. And in the log files it is not showing the any issues.

 

Could you please let us know the reason and inputs for this behaviour

 

Thanks

Srinivasa
