I don't think this is an OS thing at all. That error messages is pretty
associated with this code:

#define MaxAllocSize    ((Size) 0x3fffffff)        /* 1 gigabyte - 1 */

#define AllocSizeIsValid(size)    ((Size) (size) <= MaxAllocSize)

If malloc failed you'd get an actual out of memory error, not a notice.

We need more information from the OP about what they're doing.
