Server goes non responding state

zaeem · 12-07-2010, 04:10 AM

Dear All,

I am using CentOS 5.5 (64 bit) on a Quad core server having 8 GB RAM. This server has MySQL server 5.1.47 installed. THis server goes non responding state after every 20 to 60 days. SSH, telnet doesn't work at that time however PING works fine. I have to hard reboot the server to get it back on track. Can anybody let me know what logs/files should I look into to find out that what happens to the server when it went to non responding state?

Any help will greatly be appreciated.

Might be nice to start with /var/log/messages

/var/log/messages is not giving any clue.

Any other log?

Is it going into power save mode (ACPI)? My system has a pm-powersave.log.

The ping could be handled at a lower level, or perhaps even your modem, router, or NIC. If it isn't in this state, are these process still running and are they still listening? Assuming here that it hasn't crashed and locked up the keyboard.

I don't see any such log file. Anything else I should look into?
