Also check between_bytes_timeout. In 2.1.5 it defaults to 60 seconds. It
wasn't enough for some requests on my platforms.
One might think that 60 seconds in between bytes is bad enough for a web
application, right? ;)
No worries, those requests where made by machines, not humans...

Anyway, as Tollef also suggested, check your timeout settings on both ends
(varnish and backend).
