I can bet it's NIC related problem, probably your re0 is sharing IRQ
with something and it's going up/down. The time you see (~3.oo AM) is
the moment periodic works, so it doesn't mean the problem happend then.

I've seen similar problems on cheap PC hardware with integrated NIC
and/or external PCI NIC (re/rl/em). Search for 're0: watchdog timeout'
on google.

The solution is to replace re with something else - em for example, but
there is no guarantee it's going to work - I had same problems on
crappy hardware with two identical interfaces plugged in (some model of
em - IRRC Intel PRO/1000 GT)
