I just monitored the memory resources.
During the 10-minute sequence when a load of 25 users was on the application, the usage was shown as follows.
Swap-out rate, Swap-in rate, Page-out rate and Paging rate was almost towards the 0 on a scale of 100. Page-in rate kept changing, alternating between 0 and 25, an up followed by a down, with an average high time reaching 20. Would this data help?

Thanks for the response.
Servlets and JSP are being used here.
The exception line goes something like this.
2003-07-01 19:27:29 - Ctx (): IllegalStateException in: R ( /) Current State = FLUSHED, new State = CODING
I tried monitoring the memory usage while the test was in progress. It always shows a minimum of 10% unused at any given point of time and is infact constant at that usage.
There are also lots of java.lang.StackOverflowErrors shown in the console.
Any idea if it is a memory leak problem? Could it be one?

Hello,
I am on a RH Linux AS 2.1 box,
working with Apache 1.3.27 configured with SSL, tomcat 3.2.4
and jdk 1.4
When I load test the web application we have here with concurrent users working away at it, over a period of time, i get the following errors on the tomcat console.
1. IllegalStateException in huge numbers
2. java.lang.OutOfMemoryError errors
Subsequently, tomcat gets shutdown displaying the following messages.
2003-06-21 19:10:17 - ContextManager: Error reading request, ignored - java.lang.OutOfMemoryError
<<no stack trace available>>
2003-06-21 19:10:17 - PoolTcpEndpoint: Endpoint ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=8080] shutdown due to exception: java.lang.OutOfMemoryError - java.lang.OutOfMemoryError
<<no stack trace available>>
What could be the problem? Could the application be having any memory leaks? Could someone give me any ideas/suggestions?
Thanks
