[squid-users] [squid-users]: WARNING: Disk space over limit: 31457564 KB > 31457280 KB. How to avoid it?

Hello All,

I am running some polymix-4 tests with squid 2.6-S3. Every single test
I have run so far has these warning. Some FAQs and other searches
suggest that this is caused by a corrupted swap.state, and the
solution is to wipe out the cache dirs and rebuild the cache.

Is there a better solution than this, or does anyone know what causes
the swap to get corrupted. It seems odd that it gets corrupted every
single time.

I am asking since most of the tests seems to fail under load close to
the point where these messages start coming. And I dont want to wipe a
cache store in the middle of a test.
