[Linux-cluster] virtual address went down? (with panic link)

[jason at monsterjam.org]

I think the mailing list doesnt like attachments, so heres a link to the panic that was supposed 
to go along with this post.
http://monsterjam.org/crash/panic.jpg

I tried stopping the services on 
the first box of my 2 node cluster:
service rgmanager stop
service gfs stop
service clvmd stop
service fenced stop
service cman stop
service ccsd stop

everything came down fine.
then I started em back up..
service ccsd start
this seemed to hang for about 2 minutes, then I got a panic..
as shown in the linked above  graphic..

this is on  2.6.9-34.ELsmp redhat  Enterprise Linux AS release 4 (Nahant 
Update 4)
running ccs-1.0.3-0,
cman-kernel-hugemem-2.6.9-43.8
cman-kernel-2.6.9-43.8
cman-1.0.4-0
cman-kernel-smp-2.6.9-43.8
cman-kernheaders-2.6.9-43.8

 built from sources..

heres my cluster.conf

                </service>
        </rm>
</cluster>

ooh and shortly after the first box came back up, the second one got 
rebooted automagically (power fenced from the first one im guessing) for 
good measure.

any help appreciated
