Well, I don't see this from the code, so it's just a hunch, but: - I wasn't able to reproduce it on the server side with big uploads, - I wasn't able to reproduce it on the client side with buffering on, - I was able to consistently reproduce it on the client side with buffering off, - I did a fast scan on some of our production logs and I see those errors only for content that would be transferred with proxy buffering off, - I think that we would see much more complains if this was happening on the server side or on the client side with default settings (buffering on). I know this isn't very scientific, but those are the facts. Note: I didn't play around with WebSockets... They are effectively unbuffered, so they might be triggering this issue on the server side. > In any case I don't think we should commit any workarounds before > the problem is at least understood. Agreed. I should be more clear that my patch was more of a temporary work-around that a proper solution. > Trivial mitigation for the > errors observed so far would be to switch proxy_buffering back to > on, as by default, and/or use larger buffers. Surprisingly, at least on OSX, larger buffers are part of the problem. Small buffers (4k/8k) work fine, but the moment I increase the buffer size (16k+) the error is triggered right away.
