[lwip-users] sys_mbox_free error when SYN retries reached

[nikolas.karakotas]

Hi,

 

I’m using LWIP-2.1.3 and NETCONN api.

 

I’m using a single thread to do a http request that works well until I noticed an error when it was unable to connect to the server.

 

I replicated the issue by using a wrong port number and this triggers the tcp_slowtmr: max SYN retries reached.

 

Attached is a log.

 

I noticed when I call netconn_delete it throws a:

sys_mbox_free error

at line 76 ../Application/User/Src/lwip_sys_arch.c

 

I’m unsure if there is an error in the mailboxing or LWIP and how to approach this error.

 

 

Nikolas
