This is probably due to backend timeouts, I would guess? The default applayer settings being applied to wdqs include `between_bytes_timeout` at only 4s, whereas `first_byte_timeout` is 185s. So if wdqs delayed all output, it would have 3 minutes or so, but once it outputs the first byte, any delay over 4s will kill it. Although I'm surprised that doesn't result in a 503. There's probably also multi-layer interaction with https://phabricator.wikimedia.org/T128813 and the do_stream and such...
