Processes in uninterruptible sleep are counted in the load average. One of the gfs2 daemons (in early versions) was set to sleep in this way. I suggest that you should upgrade to a more recent version (simply because a number of other bugs have been fixed since then) although the uninterruptible sleep is harmless aside from its effect on the load average, Steve. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
