So I deleted swap.state files and restarted squid. After some time it
works fine (squid's current size and filesystem usage were equal).
But after 2 days it started again

Hmmmm.... strange
What I noticed is that filesystem usage never goes above 33-34%, shile
current cache size goes.
It looks like squid stops writting when fs is 33-34% of usage...
some info:
Squid Cache: Version 2.3.STABLE4
SunOS w3cache 5.6 Generic_105181-22 sun4u sparc
ps. there's no problem with inodes, I've checked it.
