Steve,

Your swap file is set too small. The default recommended size is RAM plus
12. So if you have 128 meg of RAM in your box, the default minimum would be
128 + 12 or 140 meg swap file MINIMUM. Maximum does NOT matter. If you have
plenty of disk space, make it like 500 meg max or something so you know
you'll never reach that high.
It requires extra overhead on NT to have to resize the swap file while it is
busy doing other things. So I would recommend a minimum swap of something
much higher than 140 meg. Assuming you have the disk space, I would use
something like 250 meg min and 500 meg max or whatever so NT never has to
resize it during operation.
It is normal for NT boxes to use up RAM over time so all you can do is set
the swap file correctly.

Good luck...
