Nope, wasn't me. It had been somewhere around 250 days that the server had been up, so a restart was definitely required, but if the server locked up, my host has no way of knowing. This is an unmanaged server. They just supply power and an internet connection to it, that's it. and yes, it's dedicated so no other machines are on my server. so I'm thinking they may have had a power outage which should have full time power backup. They just installed brand new Diesel Generators a couple years ago. Not sure, is what it is I guess.
