I just hosted a game on Wormnet, generated a double level cavern map, and as soon as someone joined, an "out of memory" error popped up.

My OS is Windows 7 x64 Home Premium. My RAM is 2 gigs, my page file is 2 gigs (set automatically by Windows), and I have about 400 gigs of free hard drive space. My RAM usage rarely goes over 50%, and wouldn't Windows give me a warning (or possibly increase the amount) if I was running out of virtual memory?

1) What's Your game version?
2) When did You update Your drivers for the last time?
3) Do You use WormKit?

Everything's updated, no Wormkit.

EDIT: Using original Microprose CD.

It may be a RAM problem, try to run Windows Memory Diagnostic (MdSched.exe).

If it's not RAM, so the problem may be caused by some background processes or by "full of trash" system.

My computer runs fine. I suspect this was one of those errors that only happens under a rare set of conditions.

Don't be so sure, if You didn't check all possibilities. I'm hosting almost all game schemes (incl. T17 and Elite) on Win7 x64 and never got this kind of error.
