[lwip-users] lwIP hangs on transfers with many short packets

[multiplex]

Hi all,

We're having a problem that stumps us. Using lwIP1.3.0 (Xilinx Microblaze
port), we are using lWIP to support a telnet CLI connection. As long as we
don't have a lot to print, no problem; once we print a lot of data
typically, this can be even packets containing 1 byte of payload, lwIP hangs
(typically, after 30-40 packets). With larger chuncks, it just takes longer.

We are using socket mode, all threads are running at the same priority.

With the debugging turned on, we see that the cause appears to be inside
tcp_enqueue which keeps going around in circles trying to
allocate/deallocate something but hitting a boundary.

Any suggestions on how to resolve this ? 
* right now, we just wait a few hundred milliseconds after each lwip_write -
but this really slows down data transfer

KR,
Michael
