Subject Out of Threads error
Date Fri, 04 Aug 2006 18:18:04 GMT
I'm getting this message from my Tomcat 5.0.28 on Linux.

2006-08-02 21:01:19: ERROR All threads (400) are currently busy,
waiting. Increase maxThreads (400) or check the servlet status

Originally I had 200 threads configured and now 400 in an attempt to
avoid it.  Either number seems larger than what should be necessary.  It
seems quite likely that there's an application issue causing all threads
to block and accumulate or something so I need to do a kill -3 next time
it happens to try and see what everyone is up to.  That said, I was
attempting to grep the Tomcat source code for where this message is
logged and thus where I hoped to find and understand better the thread
manager.  I grepped for "Increase maxThreads", "Increase", and "are
currently busy" all to no avail in finding the code doing the logging.
Is the code which logs this message part of a dependency library not in
the tomcat source tree?  If so, which one please.  I just want to
understand the application behavior when the limit is reached.

Many thanks!
