I'm guessing that you can somehow tell by looking at the stack trace whether the connections between apache and tomcat are somehow being held onto or locked waiting for something and not released. Maybe a database connection is not released? Maybe apache graceful causes the problem? Any input is appreciated.
Thanks for your help!
apache version 2.0.40
mod_jk 2.0.2
tomcat 4.1.27 and 4.1.30
I've attached the javacore file (I stripped out classloader lines since they take up the majority of the file) Let me know if you need to see those.

I think I have been having lockups around every 16 hours... 60000 seconds! So what does that mean about this configuration?connectionTimeout is defined in milliseconds, not seconds, so that is 60 seconds, not 16 hours.Is some servlet not returning content but hanging on to a connection?Could be, or could be that your server is really busy. When you look at the server-status through Apache, does it show 255 processes busy as well?Could you explain a little further about 'bug in a servlet causing it to not return'?You could either have a deadlock (synchronization issue) in your code, or an infinite loop.I have a stack trace, but I don't see how that helps me figure out where my problem might be... I'm not sure what exactly to look for.Compress it and post it to the list or put it on a public webserver so we can take a look.
