This problem with our new OES cluster started end of last year. Resources on one of the NODES would no longer be available to users. If we tried to move the resources to the other node, they would unload and then go comatose immediatly.

Other symptoms, Syncsort backup Express loses visibility of the cluster.

Only a full reboot of the whole cluster solves the problem. Nothing immediate jumps out of the logs, but they are so vast not quite sure what to look for.

Any ideas before I contant Novell support, as sadly, my experiences with them are pretty poor.
