I'd guess this as the problem. At least I found a similar thing in my
codes. I had a repetitive

bispektrum = complexarr ( 2 * cutoff + 1, 2 * cutoff + 1, $
2 * Mask_Depth + 1, Mask_Depth + 1 )

in there, and it was eating up all available memory after some time.
I had to change it to setting the variable to zero,
bispektrum(*) = null
then the problems were gone.

This was in IDL 4.01. I have never checked again if the problem is
still there...
