    [ The following text is in the "ISO-8859-1" character set. ]
    [ Your display is set for the "ISO-8859-10" character set.  ]

Ok.

Lets use the sledgehammer

on the head node

	find /opt/sge | grep -i "network-0-0"

Then the same thing on compute-0-7

Out of curiousity, what do you get if try

	qstat -f

on one of the other compute nodes?
