As you can see here I have tabs open for all 3 hubs but only the C7 (particularly when left on the "devices" page) Chrome will crash and have to click the reload and it's back up, some of the time will crash again soon after reload if I don't change off the devices page. It hasn't done that at all on either of the two C-5 hubs.
If it were a cache issue I would assume it would affect the other tabs as I am active on all 3 relatively the same amount. And they all 3 stay up 24/7. There are a total of 11 tabs that stay open 24/7 and have for the 2 years I've had HE, seems odd only 1 of the 11 would have a cache issue.
My PC had an update this morning so it did a restart and even after the restart the C7 page crashed, while on the devices page, but none of the others.
