those are good suggestions, also, can you produce a test case? as soon as you have a test case, the tomcat developers will figure it out
until then, it is hard Filip ----- Original Message ----- From: <[EMAIL PROTECTED]> To: "'Tomcat-User'" <[EMAIL PROTECTED]> Sent: Thursday, October 02, 2003 2:06 PM Subject: Re: Tomcat hanging!!

During one of your periods of inactivity, send a few SIGQUITs to the jvm (eg - "kill -QUIT <TOMCAT_PID>"). In CATALINA_HOME/logs/catalina.out you'll see a series of stack traces (thread dumps). Use these to get an idea of what an "idle" server looks like. Then, get tomcat to hang. Send a few more SIGQUITs. Look for threads that weren't in your previous listing, but appear after the hang occurred. One of these is probably the culprit. Once you have an idea about where the problem is occurring, figuring out the why may be a little easier.
