We are using RHEL 4 U4 with the GFS/CS that works for that release:
$ rpm -q rgmanager dlm dlm-kernel magma magma-plugins

dlm-1.0.1-1
dlm-kernel-2.6.9-44.9
magma-1.0.6-0
magma-plugins-1.0.9-0
Would the just-announced GFS/CS for U5 help any? Looks like a lof issues were addressed.

This usually is a dlm bug. Once the DLM gets in to this state,
rgmanager blows up. What rgmanager are you using?
(There's only one lock per service; the complexity of the service
doesn't matter...)
