FYI the details you provided support your statement that MISSes are
happening without giving any clues about why.
If it happens again,
look to access.log about which URLs are MISSing, compare with earlier
logs with better HIT rates. New URLs cant be HITs until their second
request. The ideas that come to mind immediately on this type of
behaviour is something screwed wit the disk or a sudden flood of unique
(attack?) requests.
also look to cache.log for any network problems squid is encountering,
or turn debugging up a bit to see how squid is handling the MISS
requests.
