There is problem #1. Old version of squid.
We are better able to help if you encounter problems in supported
releases (2.6stable17+, 2.7 alphas, 3.0, 3.1 alphas)

How high is the high load? If its under 650 requests/sec then I'd say
upgrade to a 3.x if its more than that you will need 2.6.

All your mentioned knobs for tuning cache are for turning off
disk-cache. Squid still uses a RAM-cache for active objects.

Try this:

There are serious security advisories out on all earlier releases.
