Very large GAMS restart file

From an actual model:

C:\projects\GFACTCOM-WebVersion\Web\scripts>dir ..\..\sims.g00
Volume in drive C has no label.
Volume Serial Number is 9EE2-A434

Directory of C:\projects\GFACTCOM-WebVersion

               0 Dir(s)  239,426,981,888 bytes free

C:\projects\GFACTCOM-WebVersion\Web\scripts>

Restarting from this guy brings the smallish 8GB server to its knees (we need about 9 GB of memory, but GAMS is very Virtual Memory unfriendly).
