Hi everyone, I wanted to post the fix that we found for this issue.
The problem was that RHEL 5.x (3, and 4 too) uses IGMPv3 by default and our network is only using IGMPv2. The server would send out an IGMPv3 packet that was ignored by the network and would not actually get to join any multicast groups until the network devices would send out a broadcast to see if any host wanted to join a multicast group. I added the following to the sysctl.conf's of each node in the cluster and this issue has gone away. # Force IGMPv2 due to Network environment net.ipv4.conf.default.force_igmp_version = 2 net.ipv4.conf.all.force_igmp_version = 2 -Jeremy On Thu, May 29, 2008 at 12:36 PM, Jeremy Lyon <[EMAIL PROTECTED]> wrote: > > I'm having the exact same issue on a RHEL 5.2 system, and have a open >> support case with Redhat.
