Zigbee Radio Turning Off and Back On

I noticed today that I got a hub severely overloaded message that went away quickly. I have never seen this issue with my hub until the recent update and nothing has changed in quite some time. I opened my system events and noticed this today. I haven't rebooted yet but I am getting ready to. Has anyone else seen this?

Like I said this hub has been stable and the only thing that is new is the hub protect and the new firmware.

Update: Rebooted and haven't seen it back yet, still monitoring.

What version are you now running? I currently have a C4 2.2.5.131, and my Zigbee radio turned off last night for about 15 min. (first time ever I believe) got up this morning and several devices were un-responsive. Also about half my devices don't show up on the Routeinfo screen, (but are working) which I think means they're more than one jump away.
will also reboot and monitor.

I knew I was forgetting to add something to the report. C7 ver 2.2.6.130. I haven't seen the issue come back yet since the reboot so still keeping fingers crossed.
