Vidar rebooted tonight, seemingly only because I opened up Firefox in a FreeNX session. What really galls me is that I was bragging to my good buddy Doug about stability and all that. "Yeah it's been up for oh lets see, 60 days now, and assuming no power flickers happen any time soon, it should be up for another 60." And then like Murphy's Law requires, I get off the phone with him, go to open my browse up to download some software and boom. My remote session locks up and I'm left sitting wondering what happened for a few minutes while the server reboots.
Short version: If it can go wrong, it will.
** Update ** (Not that anyone cares really)
Our power went down for about 3 minutes tonight and then came back on, so all in all I don't feel too bad really. Either way, it's Idaho Power's fault now.
