This is working as designed. Each HTTP request is (should be) a stand
alone request. No HTTP request relies on any other to finish.

This is incorrect. The request is being passed to the parent, but the
parent is not responding in a timely fashion (over six seconds in one
instance). The user controlling the client gets tired of waiting, and
hits "stop" or "reload" on the browser, which causes Squid to log a
TCP_MISS/000. More interpretation follows...

I don't see a single successful request made through a parent cache.
You need to figure out why the parent caches are not passing you any
data. Round robin will bounce every request to a different parent,
true, but it will not cause a request to canceled before it is serviced.
