Hi Sean,
I have exactly the same problem. Tomcat5.exe is increasing memory allocation
day by day.
you mentioned:
The memory usage of tomcat has dropped ~40% since we made that change
Would you kindly provide with a document or reference on how you did it step by
step?
How did you setup the load balancer for tomcat?
thank you
Stefano

Hi Sean
It seems as if it sort of works at the moment by the sounds of this...
Things you can try when you are board and have time:
- Does Windows JVM 1.42 have jstat ?
- Try upgrading to JVM 1.5 - (linux if not available on windows)
- run jstat every minute and you should be able to get a good look
at
users vs. memory to see if this is really the problem.
And definitely - upgrade to the 64 bit JVM as soon as possible - RAM
is cheap
Andrew
