We are using RHEL 4 U4 with the GFS/CS that works for that release: $ rpm -q rgmanager dlm dlm-kernel magma magma-plugins rgmanager-1.9.54-1 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.

Once the DLM gets in to this state, rgmanager blows up. What rgmanager are you using?
