Suddenly one of my RHEL 6 Server [VM] (serving Apache on it also) went down and when i rebooted it, i saw several of following /var/log/messages as latest before it went down:

It is connections from Nagios server with Nagios NRPE(Nagios Remote Plugin Executor) which executes checks on other hosts remotely, obviously in collaboration with xinetd. So I do not think it has anything to do with your machine been down, it is not a symptom.

But i just see that several lines only until it went down. What logs else should i check beside /var/log/messages please? –  夏期劇場 May 6 '13 at 2:30
    
Well what Nagios alerted on before server went down, and can you elaborate more on how it went down, is it became inaccessible? –  Danila Ladner May 6 '13 at 2:40
    
Server was not totally responding.. Thats why i needed to hard reset. –  夏期劇場 May 6 '13 at 4:07
