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 have the same issue with an AC-3100

I have updated to 3.0.0.4.386_48263-g80b7325 and errors seem to have gone away.

Thanks to ASUS for fix.

As of today, 11/26/2023, mine's still stuck at the same version from 05/11/2023 as stated in the OP.   😞

I'm sticking with the Merlin firmware as stated near the end of the thread - it's working like a charm.
