Tomcat auto shutdown

[henrychoi_yw]

Dear All,
I am having issue with the tomcat my Alfresco using. It auto shutdown the service randomly.
I need to SSH in and start the service manually every time when the service shutdown.

OS: CentOS
Alfresco Ver: 4.0.d

Can someone tell me why it auto shutdown and how do I prevent that happen again.

Hi,

You need to attach your log file ({alfresco}/tomcat/logs/catalina.out) to take a look at errors. I think you are getting out of memory exception

I am getting a log missing between 10:16 and 10:30

I got a message from my colleague told me cannot access Alfresco at 10:24, I started the service at 10:30. So there are 14 mins log went missing after tomcat shutdown.
Please give me a hand and see how's the log goes. It does not seems any memory error causing the issue.
I am just layman to Alfresco. My ex-colleague who has setup Alfresco left the company already.

Can you attach log file, because there is no a reason of the problem in your part of the log?

Sometimes CentOs can randomly kill a process to free up resources.  The so called OOM killer.    Nothing to do with Alfresco either.

So your process is either crashing in which case there should be some diagnostics that you need to post here,   or its being killed from the OS level which you need to diagnose and understand.
