I see Heartbeats lost, then lost contact with AP.  Investigate network connectivity between ZD to/from APs.

Is it a centralised or distributed network, if its centralised with remote AP, you may want to check you MTU.

I would set the MTU for AP communication to 1250 for remote AP.

thank for you help guys, after investigation of network connectivity between zd to aps, i got nothing. But the strange thing happened, all aps auto reconnected after 3 hours down time. And stays stable afterwards.

i think latency needed (less than 100ms for remote ap connection) got improved.
