[syslog-ng] problems with syslog-ng host filter

[Orangepeel Beef]

I've got some strange problems with trying to use the syslog-ng host
filter.  It seems that every logline matches the filter f_comware but none
of them match f_netscaler.  It makes very little sense to me.  Reverse dns
is working as the logs that end up in /var/log/remote have the correct
hostname being logged from the $HOST template.

I have a second issue that SEC does not die when syslog-ng is restarted.
 (I have used this setup in the past and have had no problems, but i
suppose things may have changed in both syslog-ng and sec since the last
time)

This is driving me crazy.. please help ;)
