Tomcat 5.0 under load

[Keith Wannamaker]

Last month I took Yoav's advice and attempted to upgrade our production 
server from 4.1 to 5.0.  The production server handles 5 - 10 requests a 
second across 300 threads.  The problem I had then, and the problem I 
have now is that the server's accept thread will die within a short time 
after server start.  I hate to think I am the only person running tomcat 
5 under a heavy load, but it sure looks that way.

I initially blamed threadpool's bulletproofing, but because 4.1.31 and 
5.0.28 share the same threadpool, and 4.1.31 runs indefinitely, there is 
a problem in core 5.0 that this load is exercising.

I very much want to be able to recommend that tomcat 5.0 is 
production-ready but since we can't run it, I certainly am not in a 
position to do that.  I have reserved the next day or two for 
bulletproofing tomcat 5.0, so the point of this is to solicit any 
comments from those who may have been faced with the same problem and 
have looked at the problem themselves.

Thanks for any input,
Keith
