I could think about the following reasons:
a) a hard crash of the Java VM (may happen when using native
code)
b) Some code calls System.exit()
c) You get to many OutOfMemory Exceptions eventually killing the
VM
--
Wat are native code? I really do not noe would u mind explaining?




In case of a) there should be either a core dump or at least some System
log. Try starting Tomcat in a console of its own and look what happens.
--
Do u mean start in command prompt?




b) Can be fighted by Starting Tomcat with a Security Manager prohibiting
   a call to System.exit(). Eventually you can trace the culprit then
   by looking for the SecurityException
--
argh again how do i configure the security manager




c) Monitor the Resource Usage of the Application and the logs 

In General setting the Debug level in the server.xml may give you
some hints (For a proper shutdown the destroy() methods of Servlets)
should be called. Hope you have enough space on your devices to log
away 4-5 hours ...

How do i set my debug level??? argh... im a real newbie... pls help...

You can see tomcat's shutdown in /logs/catalina.out
Run tail -f $CATALINA_HOME/logs/catalina.out

 Currently using 1.3.1 and tomcat 4.0.2. it shuts down like after 4-5 hours
 and i wasnt able to track why did it shutdown. I have changed my ODBC-JDBC

RE: How to log shutting down of tomcat

2002-03-05 Thread Randy Layman


Are you running Tomcat as a service and it happens to shutdown every
time you log off the machine?  If so then you are having a problem with one
of Sun's feature enhancements to the JVM.  You need to pass the JVM -Xrs
when it starts up so that it doesn't pay attention to the logoff signal.  In
Tomcat 4 you do this by editing the registry.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Apache
Tomcat\Parameters is the group of setting you will be working with.

First check your JVM Option Number X parameters to make sure you aren't
already passing in a -Xrs.

If not, increase the JVM Option Count's value by one (call this value X for
future reference).  Create a new String Value entry names JVM Option Number
X-1 and the value is -Xrs.  Restart the service, log off, and Tomcat should
still be running.

Randy
