Hi
I've looked at these but can't see anything. The server doesn't mount
or export any filesystems using nfs or any other protocol. If it helps
here are the various outputs:

Anyone have any ideas. Literally the box is sitting there not doing
anything that has been scheduled.
This happens occassionally then the load spontaneously goes down. Do
you reckon it has something to do with the raid 5?
Thanks
