Server Outage

So apparently sometime early this morning the server that hosts this site along with several others became unable to allocate memory. I'm not sure of the cause, other than after I forced a reboot of my box it came back (around 11:30CST). The load on my box was nothing but the host load was high. Host load dropped to medium but is back to high, and my load is still low. So I'm thinking it's not me, and I just got hit as an unfortunate side effect. I've tweaked a couple things which will hopefully allow the system to run a bit better under load, but I'm not sure it'll help with heavy external interactions. Sorry if your site was affected, and now you know why.
