[Linux-cluster] rgmanager stop just hangs, clurgmgrd never terminates

Hi Arwin,
I have the same problem on a two-node cluster (two KVM vitual machines)
and on another two-node cluster with real Dell servers. If I flush
iptables rules BEFORE starting cman, everything works fine. But if I
start cman and rgmanager with iptables rules, I see no services and
rgmanager hangs. Flusing iptables rules after starting cman changes
anything. :-(
I have all ports open as stated by RHCS manual, but it wasn't enough. I
still cannot find why rgmanager hangs and which rules my iptables setup
is missing, but I have the same behaviour on another setup with two
VMware virtual machines.
I don't use qdisk, clvmd nor gfs. My clustert setup has clean_start="1"
on fenced. I'm on RHEL5.2, tried both 32 and 64-bits.
Have you tried starting your cluster with no firewall?
