My Ruby on Rails site is throwing sporadic 502 errors. It is running on Nginx, installed with Passenger, and is hosted on a server running Ubuntu 10.04. It seems that the errors are becoming more and more sparse, but they're still causing a problem.
I am guessing that it has something to do with buffer size, but am not sure.
I know there are a few other questions on here from people with the same problem, but it seems to be very peculiar.
Thanks in advance for any help or suggestions. I can give you any specs or version numbers that you may need.
