Static cache size, high/low ignored.

Squid 1.1.20 on FreeBSD 2.1.7 - intended purpose a backup cache.

Squid works fine on this machine, sibling and paranting and acls working
as expected.

All it has is a one gig cache. graphs of the usage of the cache drive
show that the cache builds up to cache_swap_high and stays there,
flatlining on the graph. (mrtg is fun, also have graphs of total squid
activity, very pretty ;) )

Changing the cache_swap from 1200 (1.5gig drive) to 1000 caused it to
toss out objects until it hit the low mark (of the new value), then it
built up to the full capacity and stayed there again.

Changing cache_swap_low from 75 to 50 had no effect.
changing cache_swap_high from 95 to 90 had no effect other than to cause
it to chuck out object until it flatlined again.

In short, wtf is happening here? ;)

I have an identical install over 16gig of drive on a linux machine, which
show a nice and regular ramp up across multiple drives, then a smooth
removal to the low mark (usually at peak periods :( ).

Even tried changing the reference age to 2 weeks (instead of undefined)
which caused a minor chuck out and build up to the high mark again. and
flatline.

Other information - the cache logs are also written to this drive, causing
minor drops each night as they are tossed to another machine for
processing. (note quoted drive sizes above).
