Jeff,

Here's the results on our 968.  All of the faces are still smiling.  Except
for ours, of course, when we get the incomplete WWW transfers :(

[snip]
(1) Does this occur with a large HTML page, cgi output, or both?
(2) Does the browser report an error?
(3) Have you checked your IP buffer pools to see if they have been
exhausted?  This is my strongest suspicion.  To check this:

   :nettool.net.sys "resource;display;quit"

If any of the "high" marks meet or approach their "max" this could be
the problem.  [Trivia note:  Only last year did I discover that the
output of this display has "smileys" [ :) ] at the end until you get
close to the max, then they change to [ :( ] frowns!].
(4) Can this behavior be duplicated with another BSD sockets example?

Given all of the file transfer functions (FTP, WRQ, DSCOPY, etc) we
should have hit this long ago if it were a simple buffering problem, but
they all use NetIPC.  I can't think of an immediate example of a BSD
example that would do such large transfers other than httpd.
