I have no clue what’s going on here, but I was having lots of trouble with my C7 and 2.4.x running out of memory and spontaneously rebooting. I updated to 2.5.0.143 and it performed perfectly for ten days straight, no reboots.
I updated it to 2.5.0.153 yesterday evening and it just rebooted with a low memory warning again, less than 15 hours later. No other changes have occurred.
I’ve reverted to 2.5.0.143 again and we’ll see where we end up.
