I've finally had a chance to test this and see that it indeed fixes outright error. However, I now see the following messages appear every 10s:

20150821 15:54:37.994 err syslog(syslog-ng):Error resolving hostname; host='tester'
20150821 15:54:37.994 err syslog(syslog-ng):Initiating connection failed, reconnecting; time_reopen='10'

Is there a way to change the timeout? Is this the time-reopen global option? Besides DNS lookup retries, what other operations are subject to this timeout? Finally, the default (3.7) OSE documentation indicates the time-reopen default is 60s (not 10s like I'm seeing).

Thanks,
