amavisd-new postfix issue

[dave]

Hi,
    I've got a FreeBSD 5.2.1 box running postfix 2.1, spamassassin 2.63,
amavisd-new-20030616.p9, dcc-dccd-1.2.48, and razor-agents-2.40 all
installed via ports. I'm having issues with dcc-dccd and razor-agents not
working, but i believe that's due to my firewall, anyone know what ports
they use, and that's not the purpose of this. I've got amavisd-new as a
postfix content filter. It sends messages through spamassassin and an
antivirus program, spamassassin interfaces with razor and dcc, which until i
get those ports i've disabled. My problem is with amavisd-new, when i have
the content_filter line uncommented in main.cf smtpd throttles itself,
comment out that line and it works fine. I have no idea what the issue is, i
manually run amavisd and it does not report any syntax errors. The below is
the strange error i'm getting. I don't get any startup errors from either
amavisd-new or postfix, and this only occurs when the content_filter line is
uncommented.

Any help appreciated.
