CCR2004-1G-12S+2XS rebooted by watchdog

Dear Forum,

i am facing a issue that the router is rebooting without any reason.

system,error,critical router was rebooted without proper shut
down by watchdog timer

The Router rebooted itself 3 times in the last 6 weeks. I was not able to see heavy load or power loss.

Firmware and Packages is: 6.48.3

Does anyone was facing and or solving that issue?
