This feels like the same bug that I mailed about a while ago. I 
noticed that decreasing the chunksize makes it trigger more often, and 
while transferring a large file (DVD iso) it occurs more often at the 
end than in the beginning. This goes for both my Linux test client 
(UP) and my AIX 5.3 client (SMP).
