[cvsnt] Out of memory on checkout

[Matthew Rich]

I'm getting an out of memory errror on a file during a module checkout from a branch, but I can check out fine from HEAD and from another active branch.  THis is a binary file of about 6MB and the archive size is 220Mb.  Earlier this week I could just rerun the checkout command and it would complete now I cannot complet the check out with the error.  DOes this sound like oft mentioned Winodows memory issue of maybe a corrupt archive?
thanks
Matt
