    lwip_send + MSG_DONTWAIT, blocks forever



      calling lwip_send does sometimes block forever where my understand is that the MSG_DONTWAIT flag should make sure the call never blocks at all.  I am using the WICED SDK Version 2.4.1.


      Within the lwip_send function the netconn_write is what blocks:


      err = netconn_write(sock->conn, data, size, write_flags);


      What are the reasons this call could block?
