This seems to be a rather persistant kernel bug, if so.

Since there are FD leaks in the debian stable (squeeze/6.0) packaged
version of squid3 (3.1.6-1.2+squeeze1), we pull the squid3 package from
testing (wheezy/7.0). Therefore the testing repo is already added to
our squid servers, so I installed linux from testing as well (linux
version3.1.0-1-amd64).

I tried both with IPv6 enabled and disabled, which you do by adding
this line to /etc/sysctl.d/disableipv6.conf

   net.ipv6.conf.all.disable_ipv6=1

neither case worked. Are the kernel developers aware of this bug you
mention, and is it solved in a even later version of linux?

This is something we would rather not have to do because of a single
site (out of several thousand requests per minute from our users)
supposedly triggering a kernel bug, even though this is an important
site for our sales department, our environment is hard to maintain as
it is. We'd rather stick to the, by the debian project, pre packaged
software as far as we can.

Can I provide you with any other information, not yet given?
