problem with server hang up
my server sometimes bug and I get the a lot of message like this :
ChkServd Version: 15.3 please help
HANG: chkservd on xxxxxxxxxxxxx
The chkservd sub-process with pid 30261 ran for 7455 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".

Hello :) You should review the time stamps in /var/log/maillog and match up the failure messages to the times that Chkservd reported the issue. You may need to browse to "WHM Home " Service Configuration " Mailserver Configuration" and increase the "Number of Spare Authentication Processes". Thank you. 0 -

The load here is likely the culprit. You will need to investigate what is causing the high load average. The following thread is a good place to start: Troubleshooting High Loads On Linux Systems Thank you.0 -
thanks for response. I get an email error every 5 minutes now ! 0 -

Yes, addressing the load issue is likely the best way to resolve this issue. Thank you.0
