XT8 unexpected upload traffic from the router

[Da22a1]

After noticing poor network reliability I've found that my router appears to be uploading massive amounts of data at about 50MB/s for periods of about 1min, stops for just under 1min, then starts uploading again.  When this happens there is no evidence of any device on the wireless or wired network uploading any data, which suggests it's the router doing this.  I have 3 XT8 devices in the mesh, but when this upload happens, it continues even if I switch off the other 2 nodes, so it's definitely the router doing it not one of the nodes.

Rebooting cures it for a while, but sometime later it starts again.

All devices are on the same FW and upto date with version 3.0.0.4.388_24668-gb5d7304.

It's like the router is launching a DoS attack on itself!

Any help or clues as to what might be wrong would be helpful. I haven't yet factory reset the device, that's my last resort.

I did a factor restore,  upgraded my router and two nodes to the latest version:  3.0.0.4.388_24668-gb5d7304 and did all my configurations over (i.e. did not restore configs).    My router has been stable since this morning.

If downgrading fixed the problem for mainegeek, it might be worth trying that. Also, monitor for any unusual settings or connected devices that could be causing the upload spikes.

My problem might have been fixed by performing a System Reboot from the App. It's been working  for 3 days now without issue, still using the latest firmware version.

It seems that hard resetting the router with the power switch might not have been resetting the router fully. I wonder if the router was trying to upload power failure diagnostic data to Asus but failing?!   

Fingers crossed that it was just a problem with the firmware update that required a "soft" system reboot.

Lasted 7 days then the original problem returned. Now going to try rolling back the firmware.
