Got into same situation myself and replying mostly for documentation
since your original post was quite some time ago.
Found that Apache was closing keep-alive connection improperly in some cases
(at least this is how I understand keep-alive).
Varnish sent request during keep-alive session,
Apache closed connection in return.
Apache configuration "KeepAlive Off" solved it for me.
For complete details I posted my findings here:
