What is the servlet error?  I mean, what is the underlying error?

It could have to do with servlet code that is not thread safe.  Perhaps
there is some method that destroys an object, which is currently needed by
someone else who is running another thread in the servlet.. this would throw
a null pointer exception, which would probably bubble up to a servlet
exception.

Subject: [pro_jsp] Tomcat 3.2 Problems


Hi,
I am using Tomcat 3.2.1 along with IIS 5.0 and JSPs in
my applications. However when too many users (3 or
more) run the same application and try to navigate
thru the site, the load on tomcat seems to increase
and it gives a servlet exception. Once the user
refreshes the page it works fine. This specifically
happens when two people hit the submit button on a
form at the same instant.

What could be wrong? Is Tomcat not stable for a huge
load? Will switching to WebLogic or JRun solve the
problems?
