I think sometimes xend hangs for a while. 30 seconds should be good.

What is your stop action timeout? I use 90.

There are some old bugs related to spurious resource stops; make sure 
you're running at least cluster-glue 1.0.6 and pacemaker 1.1.2.1. I 
don't see these versions in the SLES11 HAE SP1 updates repo, but maybe 
the fixes were backported to other versions. I've been using the 
packages from here:
