--------------------------------
Config :	F4810 - OpenFirmware version 5.12.6 (11/14/01 16:09)
		s81_50 
		MPxIO and IPMP configured

When configuring IB8 back into system, I occasionally get the following sequence
of messages written to the console -

 in.rdiscd[142]: setsockopt (IP_MULTICAST_IF): No route to host
 in.rdiscd[142]: Cannot send multicast packet over interface qame1-d (129.146.234.239)
 in.rdiscd[142]: sendto: Bad file number

With continued DR operations (in a loop) this is later followed up with
similar messages during the disconnect operation -

 in.rdiscd[146]: setsockopt (IP_MULTICAST_IF): No route to host
 in.rdiscd[146]: Cannot send multicast packet over interface qame1-d (129.146.234.239)
 in.rdiscd[146]: sendto: No route to host

The IPMP setup is -

lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000 
hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 129.146.234.231 netmask ffffff00 broadcast 129.146.234.255
        groupname test
        ether 8:0:20:9b:3:eb 
hme0:1: flags=9040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER> mtu 1500 index 2
        inet 129.146.234.232 netmask ffffff00 broadcast 129.146.234.255
hme1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 70
        inet 129.146.234.237 netmask ffffff00 broadcast 129.146.234.255
        groupname test
        ether 8:0:20:bf:ea:96 
hme1:1: flags=9040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER> mtu 1500 index 70
        inet 129.146.234.239 netmask ffffff00 broadcast 129.146.234.255

which is created by the following entries -

# cat /etc/hostname.hme0
129.146.234.231 netmask + broadcast + group test up addif 129.146.234.232 deprecated -failover netmask + broadcast + up
# cat /etc/hostname.hme1
129.146.234.237 netmask + broadcast + group test up addif 129.146.234.239 deprecated -failover netmask + broadcast + up
#

These messages do not appear to have any effect on the system, or the DR
operations.
