Some images randomly fail to load - receive PHP sourcecode instead

Hey everyone,

I've noticed that some images just randomly fail to load in my galleries, thumbs and full-size images included.

I was trying it out on Moon River Photography, and noticed that some thumbs were returning a 404 response from the server. I refreshed one of these 404'd thumbs about 10 times and it loaded correctly each time, but on the next refresh it sent me back un-interpreted PHP code instead!


I think that one or more of the machines you have in the cluster for rendering images is not configured properly, so the portion of requests that hit it get mangled like this one.
