We have implemented load clustering to manage the website load.
First of all I would like to explain the load balacing architecture which is as mentioned below:

Load balacing architecture description:
For load balancing we have used apache 2.0 web server and 3 apache tomcat application server and a Mod_jk connector which actis as bridge betweeb apache web server & 3 different tomcat application servers. This set up is running on a single server running with Windows 2000.

Below is the variable setting details:
-server -Xmx1024m -Xms1024m


Problem description:
Many a times, client's request doesn't get processed by any of the tomcat because of any mysterious reason.

i would really appreciate if some one can assist me in identifying the problem.

Thanks in advance.
