Subject: Tomcat 3.1 JVM exiting frequently

> Hey, guys - hope you can help with my problem here.  I'm running Tomcat 3.1
> standalone with default pooled connector settings on NT 4.0 SP6 with Sun JDK
> 1.3.  The problem is that the process just completely exits about once a day
> (obviously not good.)  There's nothing negative in any of the logs.  I'm only
> running two servlets with very low traffic (currently in testing.)
> I'm trying to figure out what's causing it to dump.  It seems like sometimes it
> stops even when the server is not being hit.
> Question:  If the servlet code generates an unchecked exception (NullPointer,

> them?  If it DOES cause an exit, I don't suppose there's any way to make Tomcat
> log it before it dumps?  I wrote an NT service wrapper for Tomcat (though I now

> STDERR/STDOUT to files, but we're trying to roll this into production this week
> and I'm trying not to use the extra time.
> Sorry that's not much to go on.  I've been running Tomcat 3.1 on an AS/400 in

Mine shuts down every hour!
I'm using W2K, Sun 1.22 and HotSpot 1.
