Re: [lwip-users] endless loop in netconn_write

We've been studying the debug info the lwipstack provides and noticed that this 
happens with multiple threads to the stack.

Sometimes a "tcp_receive: received FIN" isn't followed by
TCP connection closed 3613 -> 80.

tcp_pcb_purge

This would mean the buffers aren't purged and wouldn't this end up in 
a loop in netconn_write() because len = 0 due to unpurged data in the send
buffer?
