-----BEGIN PGP SIGNED MESSAGE-----

Hi folks,
since several months I get the message "Can't create new socket: Address
family not supported by protocol" several times the day. It is only
freshclam that acts this wrong, no other tool/service has this problem.
The machine I use freshclam is IPv4 only; no IPv6 is compiled into the
kernel. Additionally the gai.conf say to prefer IPv4 over IPv6.
Unfortunately, the resolving of db.de.clamav.net (that I use, see below)
gives half IPv6 and half IPv6 addresses. There is a IPv6 only DNS name
but no IPv4 only DNS name.
I didn't also not find any solution to force freshclam to use IPv4 only.
- From that fact and that freshclam is running every hour, the change to
get the message is pretty high.
It is also notable that this has started several months ago.
Do you have any idea how to stop this annoying message without silenting
also real errors? Any idea how to force freshclam to behave like all
other software and just ignore the IPv6 addresses if there is no IPv6 on
this system?
Here is my config:

Note that the system has different IP outside, that is just the
internal IP. But the whole stack has no IPv6 at all and will not in
foreseeable future.
