We usually depend on previous debug messages to figure out what happened, but there wasn't anything unusual in the logs you posted. I'm going to be adding some extra debugging to help narrow this down, but that's not slated until RHEL4U5. Dave -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
