There’s already an NRPE server running (PID 111111). Bailing out..

I installed nagios client  before.But when ı want to start client service.It does not start.

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

I found this error of my syslog.

There's already an NRPE  server running (PID 111111).  Bailing out..

And find this PID

root@demop_cls1:/var/adm # ps -aef |grep 111111
 root 1111114063448 0 Jun 22 - 1:54 /usr/sbin/clcomd -d

Answer;

Find this file

ls -ltr /var/run/nrpe.pid

-rw-r--r--    1 root     system            8 Jun 17 11:05 /var/run/nrpe.pid

and move it

mv /var/run/nrpe.pid /var/run/nrpe.pid.old

And again try to start

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

Its resolved.
