Comment(by martin):

 What you are seeing is a timeout waiting for the response on a reused
 backend connection (Varnish will try to reuse backend connections when
 they are marked as supporting this). Does your backend logs give any
 indication about why the request isn't being served?

 Also do you have any Varnishlog output from a connection when you are
 using Content-Length? Would be interesting to compare those.
