Don't know... (Score 1)

Every once in a while, my IPCop box (Celeron 533MHz, 128MB RAM, 5GB HD, running headless just doing routing to two internal subnets plus VPN when I'm out of town) would become completely unresponsive (HTTPS and SSH would time out, no Internet access). It didn't happen often, but enough to annoy the family. The only thing that would fix it was a hard reboot. I have it reboot once a week and all is well. That was a while ago (well over a year now), and it may have been a bug or quirk that has been fixed since. Either way, it's unintrusive and keeps my intranet humming along.
