Dear jaikiran, Sorry for posting the entire log. As you may notice, my scheduled job runs exactly at 1:00 a.m. And at the time 01:02:12 , you could see the following log: 01:02:12,192 INFO [Server] (main) JBoss (MX MicroKernel) [4.0.4.GA (build: CVSTag=JBoss_4_0_4_GA date=200605151000)] Started in 55s:542ms And I suppose this message will not occur as the JBoss has already started before, so that's why I think that the JBoss has restarted itself. How do you think about this case? Thanks if you could provide me with a solution. Best Regards, zwind View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4178671#...
