You can think of TCP_DEFER_ACCEPT as an implicit application close()
after a certain timeout, when not receiving a request. All HTTP servers
do this anyway (though I think technically they're supposed to send a
408 Request Timeout error it seems many do not). It's a very valid
question for Juniper as to why their box is failing to fill requests
when its back-end connection has gone away, instead of re-establishing
the connection and filling the request.
