Description of problem:  I have a server with Redhat OS of RH9.  I have install 
sun jdk 1.5, Tomcat 5.0.2.8, and a J2EE application called MatrixOne.  The 
application works fine when Tomcat is first started. In other words I can log 
into my application and navigate through it with no errors.  But if I leave the 
application alone for a couple of hours, I can't even get to the Login page.  
The screen is just blank.  Tomcat is still running but is not responding.  I am 
running Tomcat on port 8090.


Version-Release number of selected component (if applicable): RH9


How reproducible:
Does it everytime.


Steps to Reproduce:
1. Start the Tomcat server.
2. Log into my application.
3. Leave it alone for 2 hours.
4. Tomcat hangs and won't display the Login page.
  
Actual results:
Blank page.  Looks like it is hanging.  Looks like a port collision but this is 
the only thing running on 8090.

Expected results:
Tomcat server should keep running and display my application Login page.

Additional info: Tried a few things but no luck.  Adde LD_ASSUME_KERNEL=2.5.2 
to catalina.sh but still no luck.
