Tomcat stops suddenly without any errors
Hi All
I am using Tomcat 6.0.18. It's running fine for past two months.
Suddenly it stops and i couldn't find any errors.
The messages i got in catalina .log are
Mar 16, 2010 5:48:00 PM org.apache.catalina.core.StandardService stop
INFO: Stopping service Catalina
Mar 16, 2010 5:48:00 PM org.apache.catalina.core.ApplicationContext log
INFO: Closing Spring root WebApplicationContext
Mar 16, 2010 5:48:02 PM org.apache.catalina.core.StandardWrapper unload
INFO: Waiting for 1 instance(s) to be deallocated
Mar 16, 2010 5:48:03 PM org.apache.catalina.core.StandardWrapper unload
INFO: Waiting for 1 instance(s) to be deallocated
Mar 16, 2010 5:48:04 PM org.apache.catalina.core.ApplicationContext log
INFO: Closing Spring root WebApplicationContext
This is the second time i am facing this issue. There is no out of
memory errors.
Nobody can access my box and there is no way for explicit shutdown.
In what scenarios , tomcat will stop gracefully without any errors.
Thanks for your help
Thanks
Siranjeevi

Hi Charles
Thanks for your reply.
I understood that if the thread is killed, tomcat will stop.
In my case, there is no explicit killing of thread. Only after
graceful stop of tomcat, this thread got killed.
Thanks

You're not running Tomcat in "another JVM" - it's running in the same one your thread is running in. If you don't keep that thread alive, the JVM will shutdown, taking Tomcat with it.

Hi Warnier
Thanks for your help.
I am running tomcat in Windows platform.
I am starting tomcat under a thread inside another JVM by calling
Bootstrap.main("start");
Thanks

It would probably help if you mentioned on which platform this happens,
and if it is a Windows system, if Tomcat is running as a Service or
otherwise.

As far as I know, only when it is told, gracefully, to stop.
With an OOM or any other error, you would either not have any messages,
or a lot of ugly ones.
But if it was running under Windows as a Service for instance, a "net
stop Tomcat6" would be one way.
In that same case, a network sysadmin could also do this remotely.
Any local process connecting to port 8005 and writing the string
"SHUTDOWN" to it would also do that.
A web application running within Tomcat and doing a "system.exit()"
/may/ also do that, though I don't know if then you would have a nice
orderly shutdown as per above.
