Asterisk gets behind in processing the good responses, and the calculated RTT time for GOOD peers starts exceeding the maxms threshold, then the GOOD peers go offline too. Big snowball comes rolling down the hill and all is lost, all peers start flapping reachable/unreachable, and a quick restart of asterisk calms it down.
