I am running Freebsd 10.0, with Postfix, Dovecot, MySql, and Spamassassin 3.4.0(Perl 5.16.3). This is the second time this has happened to me. All ran fine for roughly 410 days, then Spamassassin stop flagging emails, and has all kinds of errors in the log. Nothing was touched on the system other than restarting daemons from time to time. No upgrading, no nothing basically.
Now all the sudden, I get this in my spamassassin.log May 19 10:06:34 my spamd[82620]: Argument "" isn't numeric in numeric lt (<) at /usr/local/lib/perl5/site_perl/5.16/mach/NetAddr/IP/Lite.pm line 827.
