Take a good look at the machines that are trying to use squid (from
which both directions and location).

I can think of two immediate possibilities, which may or not be right.
You are the one in a position to know and test.

1) You have a few(?) machines configured to use a proxy for updates or
something. When the squid is off they can't do anything (low bandwidth)
but when its on they do their thing.

2) Is there a rule at the FW capping web usage for users or their
netblocks , but excluding the server you have squid on? Heavy users
getting a free web access would explain it.

You will get a better idea yourself of whether its the above or
something else by looking at the connections to-from squid when its active.
