Shouldn't happen , I think.
What SQUID version are you using ?
On which platform ?
Are you using internal or external DNS setup ?
What does cache.log say about the DNS tests during SQUID startup ?
What does cachemgr -> 'Internal DNS statistics' have to
say during runtime.
Look at rate increase of dns reqs/sec. Well, you'd have
to calc. the rate kind of manually by looking at the stats for
a second interval rate, during a certain period.
The values dns lookups/secs is not present as such.
