Re: [lwip-users] Question about socket send

[address@hidden]

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

http://savannah.nongnu.org/bugs/?25882

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.
