Allan,

Sounds like a vfp memory leak

Do you use chrtran() frequently in the program ?
Do you use SafeArrays which you do not destroy ?
Do you use api handles which do not get closed properly ? (eg internet/ftp/, ...)

Also [ though this won't solve it ] try to set sys(3050) at the start of your main - it will make vfp less hungry for memory
=sys(3050,1, 64 * 1024 * 1024)
=sys(3050,2, 16 * 1024 * 1024)
