Re: [lwip-users] lwIP 1.4.1 server's SYN flood hang, no backlog

In lwip_stats.tcp I see (non zero values):
- xmit 2478
- recv 2341

but in 'sys.mbox' section:
- used 21
- max  22
- err    782

Could you tell me if you see anything incorrect in my opts (maybe any other
opts needed)?
#define TCPIP_MBOX_SIZE                      64
#define DEFAULT_RAW_RECVMBOX_SIZE      0
#define DEFAULT_UDP_RECVMBOX_SIZE      8
#define DEFAULT_TCP_RECVMBOX_SIZE      16
#define DEFAULT_ACCEPTMBOX_SIZE         16
