Server crashes related to Hang of chkservd

[gregbtr]

I'm having server crashes under a fairly light load, maybe 100 visitors active on a 300kb sized page. My server has 6 ghz CPU and 1880MB ram @ vps.net, so it should be able to handle much more.

I have gotten a few emails that say chkservd is hanging and causing the server to crash. Not sure if this is the cause, or what.

I'm on a LAMP centos 6 server using APC caching to run wordpress.

Here's the error:

The chkservd sub-process with pid 13050 ran for 778 seconds. This sub-process was terminated when it exceeded the time allowed between checks, which is 300 seconds. To determine why, you can check /var/log/chkservd.log and /usr/local/cpanel/logs/tailwatchd_log.

You likely received this notification as a symptom of a larger problem. If your server is experiencing a high load, we recommend investigating the cause. If you continue to receive this notification, it is likely that your system is unable to handle demand or a misconfiguration is delaying restarts.

If you are sure that no misconfigurations exist, you should consider gradually increasing the following options in WHM's "Tweak Settings" feature: "The number of times ChkServd will allow a previous check to complete before terminating the check" and/or "The number of seconds between ChkServd service checks".

Any help will be greatly appreciated. My website is really taking off and I need to be able to provide a consistent experience for my users.

Thanks! :]

The root cause of this type of message is high load causing a service to respond slowly. chkservd is hanging as a result of server load, not causing server load or a crash. This should help you as a starting point for troubleshooting load:

I have done it but everything looks good. There is no other way for me to resolve this.

Have you tried following the instructions in the email alert? In particular:

If you are sure that no misconfigurations exist, you should consider gradually increasing the following options in WHM's "Tweak Settings" feature: "The number of times ChkServd will allow a previous check to complete before terminating the check" and/or "The number of seconds between ChkServd service checks".

Thank you.
