Is the bridge on a UPS? If not, borrow one and install it for a few weeks.
I suspect your problem will vanish.

Swapping out the bridge shows that it's either the bridges' firmware, or
something external--usually, a power glitch. I have UPSs on my systems,
and reliability is very good. They pay for themselves at the first
brownout.

I can't see any way anything happening on the ethernets could make
it reboot.

Good luck,
Gary
