[Linux-cluster] Nodes show up extremely slowly (or not at all)

Hi,
This is a test GFS installation on ubuntu dapper machines:
linux-2.6.23-rc3
openais-0.80.3
device-mapper-1.02.23
cluster-2.01.00
LVM2-2.02.28
When starting up, up to 'cman_tool join' all looks OK.
However, the nodes see each other after a very long time only:
root at lxserv0:~# cman_tool nodes
Node Sts Inc Joined Name
1 M 92 2007-08-24 10:14:43 lxserv0-gfs
2 M 112 2007-08-24 10:29:30 lxserv1-gfs
3 M 112 2007-08-24 10:29:30 web0-gfs
4 X 0 web1-gfs
5 X 0 saturn-gfs
root at lxserv1:~# cman_tool nodes
Node Sts Inc Joined Name
1 X 112 lxserv0-gfs
2 M 108 2007-08-24 10:16:20 lxserv1-gfs
3 X 112 web0-gfs
4 X 0 web1-gfs
5 X 0 saturn-gfs
It took 13 minutes(!) for 'lsxerv0' to notice 'lxserv1'.
As I'm writing this, 'lxserv1' still does not see neither 'lxserv0' nor
'web0'.
What can be wrong here? Is it an openais-related problem?
How could I debug the situation?
Thanks any suggestion!
Best regards,
Jozsef
