High CPU usage on 386.3_2 and GT AC-2900

[Epicflails]

Hello,

This is my first time posting so forgive me if I have not followed any instructions. I'm noticing high CPU usage specifically after reboots of the router. It seems to start a few hours after the reboot. Its intermittent as well so some reboots can be up for a very long time with no issues. We are talking about 60 to 100% CPU usage. The problem doesn't happen on stock Asus firmware. I've also tried factory reset but still the same problem. What can I do to help troubleshoot?

You could use the top command from a shell (ssh) to see what specific process(es) is consuming all those CPU cycles.

What steps to factory reset did you do, specifically?
