arc-temper and mysterious random restart

[shadowuser1234]

Hello, i have had multiple CR1000B routers that periodically restart (every few hours) shortly after installation with the following in the log:

2023 Aug 28 17:08:56 info sysup: [SYS.6][SYS] Reboot by Power Cycle/Software Fault induced

The reboot is occasionally by Kernel Panic. I have had two routers that were new that had the same issue. Does anyone know what might be going on here or what "arc-temper" means as technicians I have spoken to are not sure.

Thank you!

I can see the majority of warning and info entries here are produced by dnsmasq, which is the DNS and DHCP server daemon. I don't see a problem about that.

arc_temper, I could only guess. arc probably stands for Arcadyn, the router's manufacturer, and temper is probably short for temperature, so it is a daemon for sensing CPU and/or wireless radio thermal zones.

If you need VZ to take a look at the detailed logs on your router, kindly DM me your router's serial number.
