Hi Jun,

VFP8 and earlier do have a problem handling memory bigger than 512MB. It usually happens when processing large tables and manifests itself with error message "Not enough memory for file map" (error 1150). It's currable by reducing memory for VFP buffers with SYS(3050).

SYS(3050, 1, 512*1024*1024)
SYS(3050, 2, 512*1024*1024)

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