This is what i see in the debug logs. I have just pasted the relevant logs which show the sequence of events. ............ Application specific messages (including the next few lines), indicates that the system has been up for some time. | ............ The next few log messages show some application specific errors which probably kills and restarts the JBoss server | | 2008-05-14 19:52:01,594 WARN [be.tinc.bkw.core.tasks.NTPDaemonCheckSchedulableTask] (be.tinc.bkw.core.tasks.NTPDaemonCheckSchedulableTask.perform(NTPDaemonCheckSchedulableTask.java:62)) | Connection with NTP Daemon dropped | | 2008-05-14 19:52:01,594 INFO [be.tinc.bkw.com.ApplicationEventSender] (be.tinc.bkw.com.ApplicationEventSender.send(ApplicationEventSender.java:117)) | Sending Event: ERROR_MESSAGE | | 2008-05-14 19:52:01,594 INFO [be.tinc.bkw.com.ApplicationEventSender] (be.tinc.bkw.com.ApplicationEventSender.send(ApplicationEventSender.java:119)) | Connection with NTP Daemon is dropped.

You might have to look into what's going on in the application that has been deployed on JBoss. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4151109#...
