Hi, I checked your logcat and it seems more like a ROM problem, because not only LMT is affected. Here e.g. WhatApp is also being killed and restarted. Is it the stock ROM? It seems like all your background services are often killed and restarted because of ??? perhaps low memory, a threshold for num background services is reached (did you change that value in dev options?), or the ROM is just having some bugs! I never saw something like this on Nexus stock ROMs.
