RE: [lwip-users] Windows 7 Startup crashes LwIP and Free RTOS

[Pettinato, Jim]

Are there any lower priority tasks that should run independently of the
network traffic? If not... this is starting to sound like perhaps the
core issue is resource depletion (or a corrupt pbuf pool) leading to a
stalled stack... do you have lwip_stats enabled? If so, the stats can be
very useful in determining the failure mode. You may see that all
incoming traffic is being dropped at the link layer, for example, and
that there are no free pbufs available.

Addendum:

Reviewing the effect, i've proved that all lower priorized tasks than 
LwIP are not running anymore. These functions are completely frozen. 
Higher priorized tasks like my watchdog task are still running fine. So 
i'm really sure that LwIP somehow loops somewhere, not making a task 
yield or vTaskDelay anymore.
