So, I have been working the above bug now for a while and the latest
scenario involved me setting up a linux box so I can see if I experience
the same memory leak as I've been seeing in FreeBSD.  This has brought
about a new, different issue.

The issue I'm running into on this linux box (Gentoo, up to date with
clamd 0.95.1) is that I end up with all my clam tcp STREAM connections
sitting in a LAST_ACK state for an extended period of time, not quite
sure how long exactly, but long enough that hit a limit of about 49XX
connections in this state and clamd starts to spew "accept() failed"
messages into the log file.

Doing some digging, I found a bug from long ago where this was an issue
with the exact same setup I have (clamav-milter on FreeBSD hitting clamd
on a Gentoo linux machine) and it doesn't look like anything was
actually done about it since it's marked as "RESOLVED WORKSFORME".

Has anyone else experienced this problem?  I'm thinking I might try a
different linux distro as a sanity check, but I'd like to know if anyone
has any ideas or perhaps sysctl tweaks that I could try for this.

To note, all the FreeBSD clamav-milter clients are running clamav-milter
0.94.2, not 0.95.1 and the FreeBSD versions range from 6.2 to 7.1.
