5312 VM Swap File Overallocated
Explanation: This is an "out of memory" message that indicates that
the CA-Clipper application no longer has sufficient conventional memory
available to continue.
Specifically, this error occurs when the virtual memory system needs to
swap a virtual memory segment out of conventional memory and it has used
all expanded memory and disk space that has been made available to it.
Action: Make more virtual memory available to the application.
This can be done by making more expanded memory available by increasing
the E setting of the CLIPPER environment variable, or by making more
disk space available by increasing the SWAPK setting of the CLIPPER
This problem can also be resolved by reducing the size and/or number of
strings and arrays that are active at any one time. Probably the most
common cause of this error is the declaration of extremely large arrays
(e.g., LOCAL aArray). Note that every array element
requires memory to store (even if its value is NIL), and that the number
of array elements in an array is determined by multiplying the number of
elements in every dimension and adding the sum of all dimensions except
for the last. For example, a 4096 by 4096 array has (4096 x 4096) +
4096 or 16,781,312 elements. As every array element in CA-Clipper
requires 14 bytes, this amounts to 16,781,312 x 14 or 234,938,368 bytes-
-well in excess of the theoretical capacity of the virtual memory
Note: There is no benefit gained by reusing arrays. CA-Clipper is
much more efficient when strings and arrays are thrown away and rebuilt
often rather than kept around unnecessarily for long periods.
