If so inclined, I would contact Netgate for a problematic unit. They have had more than a few returns concerning this issue of the Celeron unit. The atom unit has now been up for 4 months with the exact same configuration without crashing. I stressed the old unit, ran memtest for a day, maxed out traffic on all the ports, I couldn't get it to choke. It was random after 2-4 weeks. The replacement unit actually crashed 5 times in the same day.
