System Cache drops instanly

I am running an application on Windows 2000 AS. It retrieves its data from
an external storage system. It does this using UNC path. There is a lot of
data (>6GB) and the application caches the info as it's used. In Task
Manager you see the System Cache rise as it should. Then all of a sudden the
cache drops all of its cache that the application was using. Sometimes the
system caches 3GB and then it goes down to a few hundred megs.

Any idea why this would be happening? Can the external storage device send
some sort of commance to W2K to tell it to flush its cache? Is there
anything I can do to prevent Windows from doing this?

Thanks.
 
You'll probably want to get in touch with the application developer.

Thank Dave. One thing I didn't mention is that we were pointing the
application to an older NAS device and it worked fine for years. We just
recently upgraded to a new NAS device and have the application pointing to
it instead and now we see the problem. The applicaton hasn't changed; just
where it's getting its data from.

We are looking into settings in the NAS device, but was wondering if it
would be possible for a NAS device to send Windows a command that would
cause this.
 
Not to my knowledge but the application developer or device manufacturer may
be your best resource on this issue.
