Well it's been long enough that I would have run into high CPU usage or crashes and everything has been very stable and CPU usage is right where it normally was.
Definitely seems to be an issue with AiProtection - at least with the latest build. I guess I'm going to have to leave all of those...
Same issue for me since 386.13 on AC68U. Every few days the router reboots itself (assuming it has been crashing from high CPU usage?). Never had this issue before. Seems like CPU usage is somewhat normal if I stop OpenVPN connection. Memory usage also seems to climb over 1-2 days from under...
