"204" ? not sure.

I would expect all negative hits to be 4xx or 5xx codes.

TCP_NEGATIVE_HIT is an web server error page which has been explicitly
marked as cacheable by its website being fetched from your cache.

It would only be a problem with your squid if you have negative_ttl set
to something higher than 0 seconds.

TCP_MISS/000 is sometimes a problem, sometimes not. It means that Squid
does not have the object cached and could not fetch any bytes from a web
server for it. May be due to the only-if-cached browser control being
sent to Squid, a persistent connection closing early, or a network failure.


Please be using
   Current Stable Squid 2.7.STABLE9 or 3.1.3
