Tomcat MBean is restarting sporadically

[jnaus]

We have JBoss successfully up and running for a while now but we have an issue with the Tomcat MBean. Every now and then it shuts down and restarts itself. We're not making any changes in the deploy folder so it can't be the deployment scanner doing this. Are there any housekeeping tasks in the Tomcat MBEAN that would force itself to be redeployed? After redeployment our webapp doesn't work anymore so, it's a pretty big issue for us.

Server output:

2004-11-10 15:09:53,417 INFO [org.jboss.web.tomcat.tc4.EmbeddedTomcatService] Stopping jboss.web:service=WebServer

etc....

Something is touching the jbossweb-tomcat.sar/META-INF/jboss-service.xml to trigger this. Tomcat cannot restart itself.

The file hasn't been touched since Jun 24th. So nothing touched it....

-rw-rw-r-- 1 jboss jboss 7624 Jun 24 17:29 jboss-service.xml

We're going to disable deployment scanning with the following line. I'll post another message if it still occurs

<attribute name="ScanEnabled">false</attribute>

Is there a log4j category we can turn on for getting debug messages on why it's redeploying?

Thanks for the quick reply,
