These messages indicates there is a malfunctioning client sending crap to
Squid.

Is this a normal proxy setup, or are you transparently intercepting port
80?

If you are transparently intercepting port 80 then quite likely the cause
is some server using port 80 for non-HTTP traffic, quite likely a
peer-to-peer filesharing protocol but there is also many other abuses of
port 80.
