[Linux-cluster] "Address already in use" messages at first startup

[Jos Vos]

Hi,

I always seem to get at the first service start after a reboot:

Aug 13 19:29:16 host1 in.rdiscd[5832]: setsockopt (IP_ADD_MEMBERSHIP): Address already in use
Aug 13 19:29:16 host1 in.rdiscd[5832]: Failed joining addresses
Aug 13 19:29:17 host1 in.rdiscd[5884]: setsockopt (IP_ADD_MEMBERSHIP): Address already in use
Aug 13 19:29:17 host1 in.rdiscd[5884]: Failed joining addresses

I have one IPv4 and one IPv6 address associated to the service, so I guess
there is one message for each address.  The address assignments seem to
work fine for the rest.

I see "rdisc -fs" running (after a fresh reboot), but the "rdisc" service
is disabled (set to "off" with chkconfig).

What is starting this "rdisc" daemon and do I need it?

Thanks,
