Hi Simon,
I think that the issue was that I was calling tcp_close() in tcp_err
callback. At least I haven't seen it since I fixed that.
I had a similar deadlocking issue that I tracked down to running out of
tcp pcbs, which I fixed by increasing MEMP_NUM_TCP_PCB from 5 to 30.
Everything seems to be stable now.
Thanks,
Jeff

Replying to myself here. This did indeed cause issues.
Calling tcp_close() on the listening pcb inside the tcp_accept callback
I occasionally get a deadlock inside tcp_remove_listener(), where the
linked list is circular: pcb->next is equal to pcb.
Anyone have any ideas for how to debug/fix this?
That should not happen. When getting such circular lists, most probably
a threading issue is the cause.
Regards,
Simon
