Your 4GL program requires more memory than is available. If your program was executing sucessfully prior to this message, examine your code to see if FREE, CLOSE FORM, CLOSE WINDOW, or other 4GL statements can release memory used by 4GL program objects that are no longer needed.
If your program was using a shared memory connection, try setting INFORMIXSHMBASE to a larger value. Alternatively, use a streams (olipcstr) or network (oltlitcp) connection. If you receive this message during compilation, a .4gl source module might be too large to compile. Divide it into smaller modules, and compile them separately. If the error persists, divide the 4GL program into smaller programs.
