Thank you for your attention, Glen!

These 2 (good and buggy) production tomcat servers run different web 
applications on different physical machines. Their hardware and operation 
systems including Windows service packs are same. Tomcat configuration is very 
similar. The good tomcat server was brand new (new installed operating system, 
new web application) and started Java 5.0 + tomcat 5.0 at the very beginning. 
The buggy one started with Java1.3 + Tomcat 3.3.1 and had ran smoothly about 4 
years. 

Regarding the web application on the buggy tomcat 5.0 server. The source code 
remain the same before and after the tomcat upgrade. The only change is to use 
the new java 1.5 compiler with option "-souce 1.4". Compiling is not a problem. 
Starting the buggy tomcat 5.0 is not a problem. The only problem is hangup 
after some user access.

All possible changes were minimized during tomcat upgrade.

The buggy tomcat server was rolled back to Java 1.3 + tomcat 3.3.1 again last 
Friday. This rollback did not fix the problem. Yesterday (last Monday) I 
removed Java 1.5 + Tomcat 5.0 completely. JDK 1.3 + J2EE 1.3 were re-installed. 
At this point, everything was rolled back to the state before tomcat upgrade. 

This buggy tomcat server has run okay by far (< 24 hours), but is too early to 
say it is fixed. If it can behave until the end of this week, I may dare to say 
it is fixed and the problem is caused by the upgrade. Maybe the co-existence of 
Java 1.3 and 1.5. Maybe co-existence of Tomcat 3.3 and 5.0. Maybe ...

Oh!  Now I understand.  Thanks for the explanation and sorry I couldn't 
help you that much with your problem.  It is strange that Tomcat 5.0 has 
been running well for a year on one server but not the new one.  BTW, 
are you running different or the same web applications on the 
good-for-one-year 5.0 server and the buggy new 5.0 one?  I wonder if the 
source of the problem is with the applications that the buggy TC is 
running rather than TC itself.
