I am unable to allocate arrays of more than 1Gb without getting an "insufficient virtual memory" error. I have an upper limit of 5Gb of virtual memory. I have never had any memory problems with NT. Any suggestions?

But at least in windows it seems it is dificult to get more than 1.7 G. So your 5G of virtual memory dont help when running a program. But still it what it sems a bit strange running out of virtual memory just with 1 G.
