Router restarts...kernel: brcmboard registered...

[tallytr]

Latest Merlin FW: 3004.388.8_4
I noticed the router re-boot on its own around every 10-20 days but last 2 days I have seen this message twice at night, the NAS sends me a disconnect email, everything works fine but
the router rebooting?
Also the May 4 date is not right, anyone?

Those are all normal messages during the boot up, as is the date and time.

the router rebooting?

Check the log messages just before May 4 for clues what may have caused the reboot.

That's the complete log:

Did you modify the default log level by chance?

That's the complete log:

You're missing lots of startup messages. If you're using Merlin's firmware I suggest you change System Log - General Log > Log only messages more urgent than to "All".

Or are you using an addon script like Scribe which mangles the syslog?

 

[Tech9]

The default log level is notice/debug as I remember. The reason for missing logs.

This this? Not using an addon script.

OK, changed to this:

 

[Tech9]

Now you have to wait for this issue to happen again so you can eventually see what is causing it.

As you're trying to diagnose an actual problem set it to All rather than debug.

[Tech9]

This is unrelated to your reboot issue.

 

[ColinTaylor]

I believe that DDNS problem has been reported many times. I didn't pay too much attention to the posts as I don't have IPv6.

 

[Tech9]

I also don't use IPv6. Asus DDNS has ongoing issues with IPv6. There is an option to disable IPv6 update in DDNS settings.

Also the May 4 date is not right, anyone?

The May 4th date is what your router shows before the router obtains an updated date/time from an NTP time server. It's normal.
