rdisc

["Jeremy Lyon" <jerlyon@xxxxxxxxx>]

Hi,

I noticed the following messages when starting services.

Jul 24 10:05:09 lxomt04e in.rdiscd[3763]:  ----224.0.0.2 rdisc Statistics----

Are these anything to be concerned with?  I noticed that /usr/share/cluster/ip.sh will either HUP or start rdisc.  On one node I see the rdisc -fs process running and on the other node I don't, but both have the errors. 

[root@lxomt04e ~]# ps -ef | grep rdis
