I have my application deployed on Weblogic 7.0 SP4. Application is running
fine for few minutes after that it does not respond to any of the client requests.
I have set the following things:

Execute Threads set to 15 and tried with 50 as well.

Heap size set to -Xms64m -Xmx128m or -Xms256 -Xmx256m and some more..

Any ideas? what could be causing the server not to respond? I don't see my client
request logged in the "access.log" either. My system has enough hard drsk memory
and RAM.

Any help is appreciable.
