Are you using uart output? I think it may cause that.

I have built simple example, just lwip with freertos, no other tasks. I am observing that ping response normally around 1ms regularly in intervals approximately 60sec gets slower to 150-200ms. Then, it continues again at 1ms. See attachment.

So far I don’t see a problem with that but is there an explanation for such a behavior?
