This is a server issue at Berkeley, nothing to do with local or user account settings.
We've been told that the current (temporary) limits are 50 CPU tasks, and 400 GPU tasks - in total, not per core/GPU this time. It's only a quick'n'dirty safety net while other problems are sorted out, and it may not be working quite as expected - but since the complete end-to-end server system can't process any more WUs than it is at present (because of the VHAR recordings from Arecibo this summer), there's not much point in tweaking it.
Sit tight, and hold on for a rough ride. Better to look for more details on the main SETI message boards.
