Oh, my goodness, does this look familiar.  I have yet to figure out what
exactly is happening.  Here are some facts, though.  I have a unixpc
running HDB retrieved from the store.  I have 3 sites with which I 
regularly communicate via uucp.  Only one of these three ever exhibits
this problem.  It is a site running 286 SCO Xenix. (One of the other sites
is also a unixpc and the third is a 386 running ESIX - Everett's unix)
My problem seems less deterministic than yours, though.  This thing
only happens when transferring really big files (>100k) It seems like the 
other site just decides to stop transmitting.  Watching my modem lights confirms
that.  The other side just stops.  Since this thing only happens intermittantly,
I just attributed it to the other guy's uucp, and left it be.  However, now it
seems that it may very well be a bug with our implementation of HDB.

If anyone has any tips on how to avoid this, please include me as a recipient
of that info.
