Urgent: 2 Machine Cluster - Failed to install socket filter

[Anshul Gupta <tech@xxxxxxxxxxxxxxx>]

Hi Everyone,

I have done streamline setup on 2 machine as described on 
ultramoney.org.
Now here is the problem,

-----------OUTPUT-----------------
active-ldirectord# ping <standby-ldirectord>
PING <standby-ip> (<standby-ip>) 56(84) bytes of data.
WARNING: failed to install socket filter
: Protocol not available
--------------END--------------------

The arp entry is there.

-----------OUTPUT-----------------
active-ldirectord# arp -a
<standby-name> (<standby-ip>) at 00:D0:B7:A0:C3:AE [ether] on eth0
--------------END--------------------

And I can ping from standby to active. The WARNING message "failed to 
install socket filter" still comes .
-----------OUTPUT-----------------
standby-ldirectord# ping <active-ldirectord>
<Replies>

active-ldirectord# /etc/init.d/heartbeat stop
--------------END--------------------


After stopping heartbeat, I can ping from active to standby,

-----------OUTPUT-----------------
active-ldirectord# ping <peer-ip>
<Replies>
WARNING: failed to install socket filter
: Protocol not available
<Reply Continue>
--------------END--------------------


Somehow heartbeat is blocking packets from active ldirectord to standby 
ldirectord and because of this ipvsadm removes realserver running on 
standby ldirectord.
I am running heartbeat-1.0.4-2 on RHL 9.0 and using mcast for 
heartbeats. What can be the problem?
Thanks.
