C-7 Hub - Zigbee Offline overnight

Hardware Version - Rev C-7
Platform Version - 2.3.3.128

This hub runs only Zigbee radio. Two other hubs (C-4 and C-7) run only Z-Wave radio.

This is the same hub where the Zigbee shut off on 9-11-2022. At that time Bobby found an error in the logs from one of my apps. I deleted that app and re-wrote it (correctly this time).
Other than that, the only changes since then are the platform upgrades and three batteries replaced.

Cloud backup not scheduled last night, local backup scheduled (and apparently ran) at 2:15 AM EDT.

Dogs woke me up at 5:00 AM EDT and I immediately noticed Zigbee devices were not responding. I let the dogs out and checked the hub - found the red message indicator with the Zigbee Offline message. No Zigbee messages in location events. Rebooted from UI, that didn't bring Zigbee back (I only waited about a minute after the system came back up). Shut down from UI, unplugged, restarted. Zigbee came back on. Let the dogs in and went back to bed.

Examining logs - last Zigbee activity was logged at 2:43 AM EDT. Seems to be a big gap in the logs between 2:53 AM and 4:04 AM when a battery report from a Z-Wave device on another hub was received.

Thoughts? Suggestions?

@support_team

Before you rebooted (i.e. when the radio was still off), had you looked at App Stats and Device Stats to see if some particular app or device was monopolizing the CPU?

I did not. This is what happens when I haven't had my morning coffee.

I know that feeling!

:coffee: :coffee:

Checking other things - logs reminded me that I applied the .128 update yesterday (to all three hubs).
