My M4 Deco's crash and go red when a large file is uploaded (c. 100mb or greater) on my connection (60mb DL / 17mb UL). Note that I use Google Drive for Desktop to do the upload and I have the upload throttled on the machine to a max of 10mb (so theroetical 7mb UL headroom so as not to ruin the connection for the other person who uses the network during the day).
If I cancel the upload, the Deco's eventually go back to normal (white light) without reset or anything else.
Note that they are in Access Point mode, with an Archer VR600 v2 used as a router/modem (wireless is off on router).
The Decos are connected via Ethernet backhaul to the router.
These are the CRITIAL error messages I get in the LOG files:

Can anyone advise whether this is a known problem or if there is a fix?
