The meaning of that stats depends on your port. I don't know if it means "mbox 
full" wehn trying to put something in the mbox or "no more mboxes left" when 
creating a new mbox (every socket/netconn needs one).

In the latter case, that would mean either there are sockets/netconns left that 
are not closed correctly (or not accepted) or there is a bug in freeing the 
mboxes somewhere (which could be in the port or in lwIP core code).
