Details

While testing Phabricator locally, I've found a strange failure case when the following criteria are met:

  • My XDebug tool is turned off (it's not accepting requests)
  • The API endpoint being called is logging an exception (error_log(<Throwable>))
  • The client making the request is using Accept-encoding: gzip (note that some other encodings also cause the issue)

In this case, a 502 Bad Gateway is returned by nginx.
Digging into the logs, I'm seeing:

upstream sent too big header while reading response header from upstream

Hopefully this is "just" fastcgi_buffers/fastcgi_buffer_size-related, as recommended here?
