I see some devices in there with massive route change numbers. How long was the hub up at this point? Every route change the device will spam out tons of discovery messages, so if this is happening over and over it can inundate all the devices on the mesh.
Your mesh looks to be very spread out, there are a lot of devices but most do not have a lot of neighbors.
You also have two sensors with S0 security. What type of sensors are those? Do they report info frequently?

You can see a few more details. I would be interested in seeing it sorted by route change with highest at the top, just screenshot the first page.
