It's known that VFP has sometimes that problem on PC's with 1Gb memory or more and limiting the buffer size fixes it. I would also like to know why.

>>You can try to limit the size of VFP buffers

SYS(3050, 1, 64*1024*1024)
>>SYS(3050, 2, 64*1024*1024)

Also try to call SYS(1104) after command that process large tables. It clears memory cache and buffers.

>>>Has anyone seen this? A client is getting this error running a VFP process on a machine that has 4 gig of memory. I don't know what is in the process. It is not my code and I don't have the source code. They just called me in to see if I have any ideas. Task Manager shows memory usage only up to around 500,000k when the error occurs, so there seems to be plenty of memory available.
