This is an indication pcb-list tcp_active_pcbs is corrupted (since there
is a loop in the list: a next pointer of one pcb points to itself). This
is most often caused by multiple threads working with the lwIP core code
at the same time (other threads than tcpip_thread may only use the
netconn or sockets api). You really should get to the bottom of this, it
will cause other problems, too!

This will not be the actual problem here, but where do you call
netcon_new()? I think the code does not allow reusing a netconn if one
connection failed...
