Which version of SLES (SUSE Linux Enterprise Server) is this? Or  
are you perhaps using openSUSE?

What was changed between Syslog-NG being restarted?

Now why do I have visions of a server that’s gone through rehab … ? 😉

Which was? Perhaps the reason and/or solution will help others.

Hi wo1769815,

my guess is that your syslog-ng daemon is running on a machine that has no 192.168.0.1 interface but only has interfaces with IPs in 10.0.0.0/8 - right? Then that “source s\_external” statement would be causing the error message you quoted… and the solution would have been to adjust that statement to reflect the IP address of the (syslog-ng daemon machine’s) interface where the remote syslog messages are received.

Regards,  
Jens
