I am using WAS v6.0.2 in a clustered setup. My WAS NDM Version is 6.0.2 as w
ell.
As a web server I am using Apache HTTP WebServer v2.0.

While testing with 10 users it gives me "Internal Server Error" (not always)
.

I tried increasing ThreadsPerChild value to 7500 but still the problem exist
s.
If i will increse the same above 7500 then while starting Apache service, it
 gives me following error...

Instead of using native Apache, use IBM HTTP Server. Internal Server Error
(500) is usually associated with application server and is a catch-all
error. Check that you have enough threads in WAS web container.

You can check the current max number of threads in WAS adminconsole.
