Three problems:
 First that is 3.0.STABLE10 running. Not the STABEL11 you say you installed.

Second (non-fatal) problem:
 Some client is pumping binary data into squid through its listening port
as a 'request'. Are you perhaps intercepting traffic?

Third (non-fatal, slow-speed) problem, IO seems to be overloading:

Are your disks full? Or just an overload of large requests at peak traffic
times.

Fourth (fatal) problem, Squid rotate/restarts and flushing it's indexes to
disk dies.

I think this is already known, bugzilla is down right now so I can't check.
First, try getting the STABLE11 to actually be the running squid. That may
solve the issue for you.
