Jeffrey,
Thanks for taking the time to give this some thought.
1. There is no place in the code that we intentionally put an exit(). I
have grepped for exit() and found nothing. The system stops in a different
place every time... the last entry in catalina.out has never been the same
(over 15-20 failures.)
2. No, we do not share jars or classes... our thought was this was a
potential for screwups and not really gaining anything.
3. Good idea... I will try this.
Thanks,
Carl

Subject: RE: Tomcat dies suddenly
I've been following this thread with interest, but haven't weighed in
since I'm doing much development these days. I have to say that I'm
agreeing with Chuck and Chris that it is a resource issue - especially
since it doesn't appear to be a problem unless under load. Also, the OOP
mentioned that it doesn't seem to occur if only the production app is
being hit. It takes someone using one of the other copies first to
generate the problem.
So the questions occur:
1) Are you absolutely positive that there is no code that could be calling
exit()?
2) Are you sharing jar files or classes between the apps? If so, place a
separate copy in the WEB-INF/lib directory of each webapp, and remove them
from the "shared" location, to insure that you're not having an issue with
one app stomping on another. The combined load on a resource in a shared
class could be overloading some built-in limit, and that class could be
causing the fail without logging an error, or you're not catching the
error to log it.
3) You have the disk space, try turning on "debug level" in all your
logging utilities and see what the apps were last doing.
Jeff
