[Interest] Program runs only on four core processors.... sometimes.

Hi, me again. :-)
Not sure about priority inversion. When I check the network with netstat -an or the Resource Monitor the program seems to run. The userinterface, which connects also via tcp to the main program does not seem to come through. When I ask uncle Wikipedia, it looks to me more like resource starvation.
Yep, just seen while I wrote this mail. The program is not frozen... erm... sort of. What takes about 2-3 seconds with four corse seems to take ~15 minutes with one core. Never waited that long before. :-(
Not the result I would like, but at least consistent with what I would expect: Too slow to be usable, but at least running. I just did not see where a real deadlock could have come from.
