Yes I did create a swap file. This was on a site with NO users! Like I said, it was probably because I did zero config and spend zero time on looking into issues aside from the swap file thing. With the next tier up ($10/month) things might have been better. Might have been better with nginx too. I'll definitely try them again, as I like the concept, so we'll see what happens!
