Currently using AC68U with 386.12 Merlin loaded.

Anyone know why dcd may use a lot of CPU usage? Based on what I can find, dcd appears to be related to Trend Micro AiProtection which I do have enabled.
Don't think I've seen this behavior before though but it has been over a 100 days since I last rebooted the router so it may be time. But before I do that, I want to understand better why this is happening if anyone can chime in.

Perhaps because DCD crashes and restarts constantly. This bug was fixed in 386.12_2 and then another OpenVPN bug was fixed in 386.12_4. Update your firmware.

Ah shoot, I should have checked the changelogs and see if it mentioned anything there... Thank you!
It happens. Also your router is perhaps telling you there is a firmware upgrade available.
