Purr-daemon , what this is about?

Hello Gurus,

Im troubleshooting a server in which it has a netboot partition from a "node0" and there is other system called "host0" . Every time host0 boots it gets by network the image from the n0.
So the thing is that on the n0 , where all the logs are stored from host0, in /var/log/messages appears the following string:

Code:

Oct 25 15:48:12 host0 exiting on signal 15
Oct 25 15:48:13 n0 xinetd[4946]: EXIT: tcpmux-server status=0 pid=22668 duration=7277(sec)
Oct 25 15:48:13 n0 xinetd[4946]: EXIT: shell status=0 pid=22365 duration=7340(sec)
Oct 25 15:48:25 n0 purr-daemon[5981]: [host0] Exit state: Running (Unpingable)
Oct 25 15:48:25 n0 purr-daemon[5981]: [host0] Enter state: Off or Unreachable
Oct 25 15:48:25 n0 purr-daemon[5981]: [Simple] No transitions for Running:AllUIsOff

As you can see, the first line, is clear that n0 issue host0 to turn off due to a timeout of a "purr-daemon" , so that question is: what is the purr-daemon on linux? and why is making the host0 to turn down unexpectedly.

My system is a CentOS 5.5

powerd(1M)																powerd(1M)

NAME

       powerd - power manager daemon

SYNOPSIS

       /usr/lib/power/powerd [-n]

       The powerd daemon is started by pmconfig(1M) to monitor system activity and perform an automatic shutdown using the suspend-resume feature.
       When the system is suspended, complete current state is saved on the disk before power is removed.  On  reboot,	the  system  automatically
       starts a resume operation and the system is restored to the same state it was in immediately prior to suspend.

       Immediately prior to system shutdown, the daemon notifies syslogd(1M) of the shutdown, which broadcasts a notification.

       The following option is supported:

       -n	No broadcast mode. The daemon silently shuts down the system without notifying syslogd(1M).

       /etc/power.conf	       Power Management configuration information file
