i just tried with 10 resources in a group and couldn't reproduce the problem :-(

you mentioned on IRC that this is the only cluster that behaves this
way... is there anything unique about it? perhaps the only one with
64-bit machines for example?
can you see if you have any luck with a group comprising only of IP addresses?
it shouldn't make a difference but i'd just like to rule a few things out.
