I've been trying in vain to crunch 2 1G+ WU's at the same time with 4 GB ram and 2 Processors.

Unfortunately, every time 2 WU's try to init, 1 fails, saying that it could not allocate 1GB of mem. I can have 2.5 Gb allocated, and try to get a second NFS WU to run with failure.

if my math is correct, 2.5 + 1.2 = 3.7gb. not 4gb. the second WU would knock out somewhere round 250mb, and come out with the allocation error.

I have 64 bit windows, so all 4 gb's should work. why isn't this then?

Fixed. I did not have enough page file. made page file higher, and both WU can work together.
