I had some experiences with freeRTOS, it crashed when there is task starvation 
or it could be some interrupt priority issues.
Where is it crashing? should be blocked somewhere...

Subject: [lwip-users] udp echo stress test with LWIP - crash LWIP

Hello,

I am using LWIP with stm32, running udp server echo in my board.
>From pc I run udp client stress test.
I noticed that with RTOS lwip get crash (it even can't ping anymore,
after stopping the stress test), but without RTOS it behaves without
any issues.
Thing I tried:
1. compiled the application with speed optimization
2. changing tcpip thread priority from high to realtime.

I can't say what exactly happened to LWIP which caused it to stop
responding to ping.

Is there any idea what else we can do or how to debug this issue ?

Thanks,
Ran
