Infinite loop.

[Ken]

Well!  I installed Baruwa -- don't even really know what it does, but it
gave me a functioning package for MailScanner, so that was a plus.  A
minus, however, was the fact that MailScanner was pegging the CPU at 100%.
 A strace turned up this:

write(2, "Use of uninitialized value $fam_listen in numeric ne (!=) at
/usr/share/perl5/IO/Socket/INET6.pm line 182.\n", 107) = 107

Googling showed that others had had this issue with Spam Assassin and/or
Amavis, and had fixed it by disabling IPV6.  Unfortunately, that appeared
not to work in this case.  So I did A Bad Thing that will no doubt come and
bite me some day.  In /usr/share/perl5/IO/Socket/INET6.pm, I tweaked as
follows:

#       next if $fam_listen != $family;
        next

(My reasoning being that if it's undefined, it's also inequal, so just go
and do it.)  And lo!  My mail, she now gets checked.  However, I have a
couple of issues with this:
- This is a crazy bad thing to do on a package-managed system.  (Thoughts
of "chattr +i /usr/share/perl5/IO/Socket/INET6.pm" float through my head...)
- What if I wanted to use IPv6... which I do?
- Have I broken anything that's not IPv6 by ignoring that one line in
NET6.pm?

If anyone's got any ideas or insights they'd like to share, I'm all ears.

Thanks,

-Ken
