Yes. We have some circumstantial info that leads to believe its probably
a bug in the way Squid uses AUFS and the underlying implementation
differences in FreeBSD and Linux. We have not yet had anyone investigate
deeply and correct the issue. So its still there in all Squid releases.

We are trying to get there :). It's hard for just a few people and
non-experts in many areas at that. So if anyone has good knowledge of
how AUFS works jump in with a feature page analysis.

What we have so far in the way of config help is explained at
