Firmware: Signature Version: 2.376 2023/10/17 - Filling System Log with errors

[Rooke]

Router: RT-AC66U B1 (AC1750); Firmware Version: 3.0.0.4.51665 ;
On Tuesday, 2023/10/17, I noticed the entire System Log filled with the same repeating errors, all starting with error: "kernel: dcd/22609: potentially unexpected fatal signal 6." The only difference between the errors is the dcd number.

I checked the Administration menu, Firmware Upgrade tab, and found that the Firmware Signature Version had been updated to "2.376 2023/10/17 09:04" which was a couple of hours before I checked the logs.

After seeing that, I unplugged the Router for a few minutes and plugged it in again and let it boot up.

The errors went away for about an hour then came back. Subsequent (4) power off/on resulted in the same situation.

The errors do not seem to be affecting the router's performance, but the problem needs to be addressed by Asus. Attached is a snippet of the errors.

I think I found a workaround.

connect with ssh to your router (example: ssh user@192.168.0.1  )

r@RT-AC66U_B1-AED0:/tmp# cd /tmp

 r@RT-AC66U_B1-AED0:/tmp# dcd 

[parse_cmd(389)] cert file "./ntdasus2014.cert" doesn't exist!

 r@RT-AC66U_B1-AED0:/tmp# touch ntdasus2014.cert

 r@RT-AC66U_B1-AED0:/tmp# nohup dcd &

r@RT-AC66U_B1-AED0:/tmp# exit

dcd is started and not killed anymore each two minutes.

Thanks! It works, no errors.

EDIT:

No errors: kernel: dcd/6131: potentially unexpected fatal signal 6
but now every 30 minutes error:
kernel: [tdts_shell_ioctl_stat:256] Recv ioctl req with op 2

Do you have a link to 386.12_2 (xx-xxx-2023)? I wasn't able to find it on Source Forge, OneDrive, or GitHub. Clearly looking in the wrong place.
