Apm disarming after each "rough" landing

I am new to the apm world and maybe this is a noob question answered elsewhere, but still can’t seem to find an answer on the simple forum search. My apm 2.6 is disarming itself after each time I land my tricopter little rougher than I would like apm disarms itself. Running apm copter 3.1 is it an intended behavior, because it started happening only today and I’ve been flying it and landing in a similar way and even crashing w/o auto-disarm…

Please let me know if is an intended behavior or my apm starts to die?
