Sometime Simpler Is Better

Two virtual machines, each with 3 cores and 4GB RAM, running CentOS 7. 
[Edit: Wait, Kururu is on CentOS 6.  Well, near enough.]

Kururu is running under OpenVZ:

While Rere is running on KVM:

Also, Kururu didn't have 3 cores and 4GB of RAM.  It had 1 core, and 1GB.  I changed it to take this screenshot - but check the uptime.

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place to store real-time stats, but they didn't expire, so over several months the cache would slowly fill up with out-of-date data.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.

Apple pies are delicious. But never mind apple pies. What colour is a green orange?
