My DrayTek 2762 syslogs have just produced some weird messages that I have never seen before on any DrayTek router

The log outputs are as follows:

Does anyone know what this log output means ?

That's a debug log that the router has recorded when the system has restarted, because it encountered a problem.

If it's causing network problems for you, I recommend contacting support with that message. Also 3.9.2 has been out for a few months at this point, so it's possible there's a beta firmware available that will resolve your issue

Thanks for the information.

It was the first time that I have ever received such a message from the many DrayTek routers that I have used.

lateset firmware seems to be 3.9.2 for the 2762 - I'll keep my eyes open for upcoming firmware updates.

Again, thanks for the info - much appreciated.
