My problem is now solved. The gocwiki did not include this particular
cause of the PeriodicHold problem. The correct answer was to remove
hanging condor jobs from the queue on the WMS as Daniele had
indicated. I suspect that several WMS' still have hanging condor jobs
queued for Bergen, I will try to deduce which and get in touch.

This problem started when our disk partition filled up and jobs
started hanging in the WN queue.
