Hi

I am using nginx in front of Apache and i got this error on error log on nginx :

upstream sent more data than specified in "Content-Length" header while reading upstream

How can i fix this?

I tried turning proxy_buffering off and that took that message away. However, I am seeing more of "upstream prematurely closed connection while sending to client" errors. Am I correct in thinking that the upstream cuts off the connection longer because it synchronously interacts with the client? Is there a way to simply ignore this warning in the logging to save io? The reason is that I don't think this warning is a serious one since I don't see the buffers running out and writing to disk.

Thank you in advance
