Hi everyone, we have a JBoss 3.2.4 app that has been deployed for some time. We restart the server every morning at 6:00 AM to clear/reset caches etc... For the last week or so, the entire application has stopped in mid afternoon. No user requests are served. The only fix is to restart the app server.
There are no unusual messages in any of the logs and nothing in the server event log either. We have gotten a couple of the "Somebody try to hack into the site!!!" events but they were earlier than the time of hang-up.
Any ideas on where to look or how to debug this would be greatly appreciated.
Uh, how much -Mx you give it?? The tomcat in one of our customers use also had the problem... but I finally found the reason is that IBM Java gives it -Mx64m... I wouldn't be surprised if it hangs up just after startup....
