Weblogic server terminated abnormally when doing web stress test

Question

Hi folks,
I used MS Web Application Stress Test tool to test our web application deployed
on weblogic server 6.1 sp2. I set the tool to run with 20 threads concurrently.
And I recorded a script with 300 requests and there are 10 milliseconds delays
between each request. After running that test for one hour or so I got an ArrayIndexOutOfBoundsException.
The welogic server was dead. I had to kill that process to restart the server.
I tried this testing procedure serveral times. Sometimes I came across the same
problem, but sometimes didn't.
The machine running WL6.1 is a Red Hat Linux server with 2 CPU and 1 GB RAM.
Does someone knows why this occurs and how to prevent this problem?
Thanks to anyone who give me some advise.
The stacktrace is below:
<Nov 14, 2002 10:58:36 PM CST> <Error> <Posix Performance Pack> <Uncaught Throwable
in processSockets
java.lang.ArrayIndexOutOfBoundsException

Answer 1

Hi Francisco,
I run MS web application stress test tool on a Windows 2000 machine as client.
It access weblogic server running on a Linux machine throught HTTP request. You
may download this tool from Microsoft web site. It is free.
