You can change the JVM option, -Xmx to increase the heap size in
catalina.sh and see if it can accomidate more requests

I forgot to give details about my Application and test.
These details might give you people an idea about the problem area.
In this app. users has to enter login ID and pwd in home page which
will be sent to a resource which validates these details, say
"LoginValidation" this resource will then forward control to the Main
Page of the Application, say "MainPage.jsp" . From main page user can
open/ request different pages(modules of application).
But my test only involves a request to "LoginValidation" followed by
request to main page.
In this app. inorder to get data about certain activities happening on
the server side into the client browser, we keep on refreshing a
hidden frame in mainpage (simply using html meta refresh ) after every
one minute, lets call this page as PollServerForData.jsp.
To simulate this i added a request to PollServerForData.jsp also in
my test plan after request to the main page (that means every virtual
user will be requesting the PollServerForData.jsp page after every one
minute)
This test worked for 1200 virtual users and failed for when tried with
more than 1200 users .
Will there be any problem for tomcat for maintaining more than 1200
sessions in memory??

You need to check on whether it is giving Outofmemory error is
immediately after starting loadtesting with 1500 users or over period of
time. If it is over period of time then you need to check whether there
are any memory leaks. Or your design for ex., it might happen if you
query db and that ends up resulting in huge number of rows.
BTW., what is the max number of threads you have configured?
and what is the active number of threads? Pbly u can use
Performance-Valve to get such details.

Hi All,
Recently we started load testing our application using Jmeter.
Following error is coming in tomcat while test is run at higher loads like 1500
virtual users etc

org.apache.tomcat.util.threads.ThreadPool$ControlRunnable run
======================================
I already configured the Tomcat using -Xmx option to use upto 2GB of RAM
(Tomcat is running on a 3GB RAM machine)
Any inputs or pointers to the related resources on this problem??
