I've deployed a rails application to media temple's grid server (for the first time) and seem to get this error (see below) after it's been up and running for a day or so. It appears as though it happens without a user action.
Any ideas?
-------------ERROR--------- Proxy Error
The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /.
Reason: Error reading from remote server
