What version of Tomcat?
What version of the connector?
Just a thought, but you might start by changing the passwords on the
server, just in case you have an angry co-worker or two.
Personally, I have run into bizarre issues similar to this but in my
case I have been able to track it down to one of the following.
(1) New enterprise firewall that would drop the modjk connections.
(2) New version of apache that required a newer version of modjk, that
in turn required new worker settings, that in turn required new tomcat
server.xml settings.
(3) Accidental deployment of multiple jar files containing references to
the same classes. In my case accidentally backing them up into a
directory under WEB-INF/lib
(4) Modifying the logging settings of the server, and misconfiguring it.
(5) Running Tomcat 6 with some of the more critical jars under
WEB-INF/lib rather than /<tomcat root>/lib
(6) NOT using the tomcat connection pool (this one caused very random
issues with Tomcat 6) (I was using an older connection pool approach)
(7) Exhausting memory on the server, or not configuring the tomcat java
process with enough memory.
(8) Running multiple conflicting instances of tomcat on the same server
(port overlap, etc)
(9) NIC card problems/dropped network connections
(10) uploading files of enormous size and not configuring for it
Do you have the option to run a test instance of Tomcat on another
server? If nothing has changed on the server, then you might just be
running into hardware problems. I had a mother board start to fail in
one of our tomcat servers and it caused all kinds of unstable
performance until we figured it out.

Tomcat is shutting down. There are no java processes on the server after this
happens. The machine itself is still up and running fine.
The servers are secured on a Linux machine behind a firewall.
The auth.logs show noone logging/sshing in when the shutdown occurs.
I'm using an Apache front end and using modjk to connect to Tomcat.
Like I said it's really weird.
I've sort of remedied it by putting "ps -e | grep java || /etc/init.d/tomcat
start" in crontab
But as you can imagine that is far less than Ideal.

Subject: Re: Weird Tomcat issue.
When you say "it" is shutting down, are you referring to tomcat, or to
Turbine.
What version of Tomcat and Turbine?
When this happens can you still directly reference "any" ports on the
tomcat server. (say port 80, etc)
What environment are you running it on (Linux, Windows)
Are you using the connector?
Things don't typically just start happening without a reason... so is
access to this server controlled? Is it only you accessing it, your
team, etc? Can you pinpoint an approximate time that it started happening?

I just recently started having this weird issue with Tomcat and Turbine.
It appears like its just shutting down cleanly, only we are NOT shutting it
down.
It's really weird. Everything seems to be running fine, there's no errors in
the logs before this happens. It's like it's just randomly deciding to shutdown.
Any thoughts?
