From reading the posts in this thread, this bug comes pretty close ("TCP hangs on MSS > pcb->snd_wnd"):


Although that was slightly different as the server never announced enough data, it's kind of related since the stack-internal source of the problem is the same (not splitting pre-created packets that are too big to be sent). BTW, it has no planned release set.

RFC 793 says:

     "Another suggestion is for the sender to avoid sending small
      segments by waiting until the window is large enough before
      sending data.  If the the user signals a push function then the
      data must be sent even if it is a small segment."

Just for information, we're also doing what is suggested for the sender
in RFC813.  I'm increasingly of the opinion that it is Windows XP's
behaviour that is at fault here, but that doesn't necessarily mean that
we should ignore the problem.
