Tomcat instability

[rsman]

My web site run under apache 2.0.43 & tomcat 3.3.1

When I do some stress test, after some hits, I obtain, for some jsp pages, a http error (500 for not naming it!).

Thanks in advance for your help

See below the error message found into tomcat.log:

tomcat 3 is severely outdated technology. I would suggest upgrading to version 5 (with at least SDK 1.4).
