Wed 02 Nov 2016 11:53:29 AM UTC, comment #1: The only real difference between the LWIP_TCPIP_CORE_LOCKING_INPUT settings is that when it is 0, you pass input messages via a message queue. So I could imagine you lose messages that don't fit into your queue. However, both this and the freeing of RX pbufs that don't get accepted are in the responsibility of your port or netif driver, so I don't think there's much chance in fixing this in our lwIP code...

Thanks, Simon. There was no buffer free in case of 'netif->input()' returns != ERR_OK. So the issue is on my side.
