Hi there!
I have the exact same problem, and it comes and goes as it pleases..
I'm testing varnish with different backends (different customers sites in
the same instance) and every once in a while it locks up at the same place
(the X-Forwarded-For header on varnishlog) for any site. Not the others
though, as they are accessible through varnish just fine. And after a while
of working the cache the site that locks up comes back to life.
This is what varnishlog shows just before the 503 error:

Any one else seeing this? Any one have any idea why this happens?
