I think this is the problem:

>x.x.x.x: End of run not found

It doesn't detect when the configuration is finished, so the $found_end = 1;
never becomes set.

Try to edit xrancid:

--
        # catch anything that wasnt match above.
        ProcessHistory("COMMENTS","keysort","H0","$_");
        # end of config
       #if (/^# End of configuration file/i) {
 ++     if (/^# Module vrrp configuration./i) {
            printf STDERR "    End WriteTerm: $_" if ($debug);
            $found_end = 1;
            return(0);
--
This will set $found_end=1 when it detects the part where VRRP is configured, which is the last part of the configuration.
It's a nasty hack, but it should work.
