Can these logs tell me whether my Tomcat is crashing or being shut down?

Andrew Trobec (497●12●140●139) | asked Feb 21 '14, 5:48 a.m.
Hello,

I am troubleshooting some catalina logs to determine whether my CLM server is crashing or whether it is being brought down intentionally by an admin or some rogue process.  Here are 4 different log extracts where the server restarts.  Can somebody help me figure out what's going on?

As you can see, there is sometimes a pause a few minutes before the server is stopped and restarted.  The fact that the server starts almost immediately leads me to believe that there is some sort of restart being scheduled.

I don't expect a definitive solution, but maybe somebody has had a similart occurance and point to something that might be causing the problem (scheduled tasks or similar)

Thanks!

Andrew, if I request a shutdown, my catalina logs in Tomcat/logs show:
INFO: A valid shutdown command was received via the shutdown port. Stopping the Server instance.

Hello Ralph,


Thanks for your input.  When you request a shutdown, are you doing it via windows service or the Jazz Team Server batch files?

Regards,

Andrew

As I usually run demo/development/test systems I start them with the batch files.
If you run a service, the service logs should tell you when the service was shut down.
