I had reported similar NetAtalk results a couple months ago, but I 
failed to do comprehensive testing and reporting (i.e. AppleTalk vs 
TCP on my various Macs, which direction, etc), since my BSD machine 
was in a state of flux. I noticed the problem because I was using my 
Mac to download pkgsrc distfiles on an AOL dialup overnight, and have 
since returned to having a "normal" connection which I can have my 
BSD machine NAT, so my dealings with the issue have subsided. I can 
say, however, that running the asun version "fixes" it so that 
everything works fine, and I still have the issue when using 
netatalk-1.6.1 and userland/kernel from -current sources March 22.

The copy seems to work fine when copying from the BSD machine to the 
Mac. The folder on the Mac HFS+ filesystem is about the same size as 
the source folder. I then rename the folder for the return trip & 
copy it back. At this time, the copy craps out partway through, and 
the folder is now Gigs large (~100MB source) according to the 
"calculate folder sizes" in the Mac finder.
