Hallo,

 

I moved my project from v1.4.1 to GIT HEAD with another port (Analog Devices
-> port from Stephane Lesage)

 

Now I'm getting at heavy load the following assertion:

Assertion "unsent_oversize mismatch (pcb vs. last_unsent)" failed at line
465 in .\src\core\tcp_out.c

 

I use following TCP settings:

#define LWIP_TCP
1

#define LWIP_TCP_TIMESTAMPS
0

#define TCP_WND
(4 * 1024)//8192

#define TCP_MAXRTX
12

#define TCP_SYNMAXRTX
4

#define TCP_QUEUE_OOSEQ
1

#define TCP_MSS
1460

#define TCP_SND_BUF
(4 * TCP_MSS)

#define TCP_SND_QUEUELEN
(64 * TCP_SND_BUF/TCP_MSS)

#define TCP_SNDLOWAT
(TCP_SND_BUF/8)

#define TCP_LISTEN_BACKLOG
0

#define TCP_OVERSIZE
TCP_MSS

 

I'm using the sockets API

My Application: Kind of JPEG Streamer which sends out  JPEG images when
receiveing correct HTTP Get (Implementation for JPEG Streamer with
singleframe requests)

 

I didn't have this error before moving to GIT head.

Anyone an idea?

 

Best regards,

Sandra
