Comment(by eli):
Here's a question: are the dropped sessions and the (null) StatSession
lines in the log consistent with a Varnish instance that is simply
overloaded? Could a large number of clients be holding a session open and
causing all my problems? I'm wondering if there's an actual or perhaps
inadvertent DDoS going on here.
I've upgraded to 2.1.4 and also tweaked my params to increase the thread
pool size and decrease sess_timeout and send_timeout and things seem to be
doing better.
