Cygwin CVS - Cannot allocate memory

Question

In creating a sandbox (checkout) from our CVS repository using Cygwin CVS and having direct filesystem access (NTFS), I am getting the error:

[checkout aborted]: Could not map memory to RCS archive {archive_path}:  Cannot allocate memory

The archive file found at {archive_path} is 1.005G (1052905061 bytes) on disk.

Doing a checkout with the same tools but using :pserver: to a CVSNT server works just fine.

Any ideas?

Thanks, mG.
