I've had some similar problems on an O2000 in Bergen, Norway. It was quite
annoying because I was freeing requests all along. I actually thought
this problem was a local one, in accordance with other
hardware/software problems we had here.

The bottom line was that I had to run the larger tests on other
machines, because I could not work my way around this problem. I would
therefore also be very interested in a solution to this one.
