Hi, Basically the continuous frames discards show the existence of high burst (used to happen on wireless) and/or high clock drift (put > get). The sample cases I mentioned before are the common cases of burst and drift. Make sure about them first (disabling PROGRESSIVE_DISCARD won't fix the discard problem if high burst and/or high drift occur).
