I have Apache 2.2.11 and a web server behind it (CherryPy). When I upload a large file to the CherryPy server, I see the file in /tmp/modrproxy.tmp.FOO It uploads completely. Then Apache returns a 502 error without ever hitting the backend (the first line of code in the handler is to spit out a log line saying it was reached). The access and error logs are below and my virtual host config. I can't think what else to try. I was using RewriteRules for this. Same situation. This is a production server and it's having problems. Any help would be greatly appreciated.
