httpd, lfd, httpd, cpsrvd, lfd failed and restarted multiple times. What now?

[tnedator]

Cpanel installed on Centos 5.2 on a dedicated server.

This morning, I received multiple emails about services being restarted. About 20 minutes apart, with nothing that I coudl see going on with the server, I had multiple services fail and restart.

How do I trouble shoot this to see if there is a problem?

At 6:21 The following services failed:

httpd
lfd
httpd
cpsrvd
lfd

and I received emailed messages similar to these (obviously the port and service name were didfferent in each email).
cpsrvd failed @ Sat Nov 15 06:21:29 2008. A restart was attempted automagically.

Failure Reason: Unable to connect to port 2086

Then, at 6:42 The following services failed:

cpsrvd
cpsrvd
httpd
lfd
httpd
lfd

and I received emailed messages similar to these (obviously the port and service name were didfferent in each email).
cpsrvd failed @ Sat Nov 15 06:21:29 2008. A restart was attempted automagically.

Are you using any firewalls like APF/CSF? Please make sure that the firewall is not blocking general ports like 21,25,80,2086 etc

Also check /var/log/messages, /usr/local/cpanel/logs/error_log, /var/log/chkservd.log for the exact error.
