 Not sure if this could be valid reason, but can it be that when squid
 goes for origin check, url is put into "private" state, invalidating
 local copy until origin reply allows it to become cached again. And if
 origin reply never comes, all new requests for same url have to go to
 origin?

 All connections forcibly closed?
