1 Pixy, just now I was trying to upload a bunch of images and got a lot of error 500's. And as I load your page, none of the images are loading.

I just got another one:

3 Sorry about that, the cache server ran out of memory.  Fixed now.

4 Found the problem - I was using the cache server as a handy place to store real-time stats, but they didn't expire, so over several months the cache would slowly fill up with out-of-date data.

Fortunately, the cache we're using (Redis) has a setting that just says "throw out the oldest data no matter what", so with one quick change I've fixed the problem for good.

Redis is pretty neat.
