[Linux-cluster] RGManager Hanging on shutdown

Hi folks,
I'm having issues with the shutdown of my cluster, background on our
cluster is this.
We have 4 Compaq 8500r's with 8 x Xeon 800mhz with 3gb of Ram in each,
we are using Xen 3.0.1 to run 16 VM's each with shared access via GFS to
a GNBD Raid5 Export.
The last remaining issue i have to work out before we look at Testing
and moving to production is this, /etc/init.d/rgmanger hangs when
shutting down any node in the cluster, all i get on console is "Waiting
for cluster services to stop", i have to kill the process to shutdown
the system, this happens on our VM or on Real hardware so i dont think
the issue lies with Xen.
Services running on each node are these
root at edward:~# cat /proc/cluster/services
Service Name GID LID State Code
Fence Domain: "default" 1 2 run -
[3 2 1 4 5 6 7 8 9]
DLM Lock Space: "shared" 3 3 run -
[3 2 9]
GFS Mount Group: "shared" 4 4 run -
[3 2 9]
User: "usrm::manager" 2 5 run -
[3 2 1 4 5 6 7 8 9]
I cant figure out why this is happening, here is an strace from the shutdown
Any help or tips to fixing this would be great
