If you do two dumps a few mins apart and the lock state of the locks with waiters looks identical then there is a real bug. If the lock state is different, or if different locks have waiters, then that suggests that the issue is contention, Steve. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
