VPS - spamd & nameserver fails


Hello, recently i have been receiving emails from cpanel saying that spamd and nameserver fails in separate emails of course.

This has happend once when running, and everytime when rebooting my VPS. I have no idea what to do, I'm new with Linux and VPS.

Now mysql and sshd failed as well and my CPU is going crazy.


sshd failed @ Sat Feb 13 14:58:33 2010. A restart was attempted automagically.
Service Check Method: [check command]

Cmd Service Check Raw Output: sshd is not running

-----------------------------------------------------

mysql failed @ Sat Feb 13 16:11:22 2010. A restart was attempted automagically.
Service Check Method: [check command]

Cmd Service Check Raw Output: mysql has failed

And so on...

Now my CPU load is reaching 3.81?!!!

Did you have check the logs through the /var/log/messages ?
This will help you trace the reason for service failure.

Those emails are sent by cPanel monitoring system called chkservd. If it sees a service unavailable, it restart the service and send an email to the administrator email ID.

You have to check the logs of respective services and figure out whats wrong with the service, for example,

Quote:
mysql = /var/lib/mysql/server.hostname.err
ssh = /var/log/messages
BTW, if you are receiving them in bulk and see if the service is working fine, you can avoid these false alarms by turning off monitoring from WHM >> Service Manager section.

In respect to CPU usage, you have to provide more details, like output of

Quote:
top c
ps -auxf

You have to SSH to your server as root to check the logs. To check the logs you can use

Quote:
cat /var/lib/mysql/server.hostname.err | more
where, | more, will display logs page wise.
