CAUSE

The server Traps because the memory manager tries to free a block of pool that had already been freed.

The problem occurs when mapping memory to hold a large file. Memory manager tries to fulfill a large pool allocation request, when this fails (usually a low memory situation), memory manager breaks up the allocation into smaller requests. If the smaller allocation requests also fail, the memory manager frees up any of the requests that had succeeded.

RESOLUTION

This problem has been corrected in the latest Service Pack for Windows NT version 3.51.
