First and foremost, thank you to everyone for your responses. I checked the MTU on both sides and it's currently 1500 so I'm assuming it's not a mismatch. My VPN is a pair of old Netscreen 5xp boxes, and I can't find anything relating to MTU or packet size in the configuration, but I'm still looking.
Secondly, to answer your question John, There is no persistent connection between the servers. I could feasibly set up an NFS share between the two but I have a sneaking suspicion that if the problem is some sort of packet mangling by the VPN during file transfers, the actual mechanism used to transfer the file will be irrelevant. However, I will set this up and test it and report back my results, most likely next Monday.

If you are using ssh do you need to use scp as well? Or is just plain copy ok?

definitive. Someone somewhere had mentioned fiddling with MTU settings, but
I'm not really sure what that will accomplish as I am unfamiliar with what
MTU is and does. If this question has been answered previously, I apologize
ahead of time. Thanks!
