Server seems to stall when last upload packet and FIN are sent together:

http://www.mynetwatchman.com/kb/netkb/warftp/pasvfail.htm

This looks like a WARFTP issue...is sending a FIN like this the proper
way to indicate that client is finished sending the file?

Any thoughts appreciated.

There was a thread on this on e2e recently.  Specifically, see:

http://www.postel.org/pipermail/end2end-interest/2001-January/000007.html

These discuss data+FIN in the last segment of an HTTP connection, but
the question is, of course, more general, and the answer that data+FIN
is legal (but probably not the statistics of how often it actually
happens) is relevant to your case.
