Aeh... load
Paste the workers.properties file and the mod_jk settings here. Are you
using prefork or mpm in Apache? Have you tuned the apache settings to match
the tomcat number of threads?

Have you ruled out issues with db conne
'd but all the database users/connections are idle.
These can be symptoms of an application mis-managing its dbcp pools.

Hello Talha,
from a quick glance at your post, do you have the same 30 max threads

Because sending 525 users through 2x30=60 max threads seems a little
bottlenecky.
Which software are you using to produce the load? Does it keepalive
the connections?

Leon

create a DMZ) and Weblogic to serve dynamic content (Struts 1.1 based Java web
application).
We are trying to replace Weblogic with T
