I have just replied to the same on the FreeRTOS forum where the suggestion of referring to our reference integration was politely declined.

For others on this list: There is a memory leak in the poster's code because the pointer needed to free the semaphore is overwritten with 0 without the semaphore having first been freed, and then there is an attempt to free the now NULL pointer. The FreeRTOS FAQ suggests defining configASSERT() when having stability issues - two asserts would have been triggered in this case.

I tried before without sem->queue=0, but all same.

I meant calling 'vQueueDelete()' before setting queue=0.

I reported both TI and FreeRTOS, but TI have not responded yet and
FreeRTOS replied "They have a own network stack", so they are not sure
about lwip.

That's strange. Richard from freertos.org used to be very acive here.
Although I admit he hasn't been lately, so things might have changed
