LWIP+HAL Library sometimes doesn't work or work and stop suddenly

Hi, friends.

Someone has already some problem with lwip+FreeRTOS kind of simply stop work suddenly?

I already checked if occurred stack overflow in some task relation with lwip (tcpip_thread and EthIf) and I don't find anything (For hour).

How example I took print screen of ping, and see that of ping is working normally and sometimes has some failures and suddently stop work and don't back nevermore.

?
