Issue::

Service cpanel restart" sometimes will give you this "cpsrvd dead but pid file exists", please disable the Iptbales firewall of your linux Box and start "cpsrvd'.

# service cpanel status
cpsrvd dead but pid file exists
entropychat (pid 30660) is running...
melange is stopped
stunnel (pid 30713) is running...
interchange is stopped
qrunner is stopped

if cpsrvd is running on the server then Iptables must be blocking the port cpanel currently running on and hence we need to disable the Default firewall of the Linux i.e., iptables.

service iptables stop
service cpanel restart.
