I was looking at our DNS traffic on the syslog boxes and it seemed to be more than I would expect. I bumped up the dns_cache value which definitely helped, and now the vast majority of queries seem to return NXDomain. So my question is, does syslog-ng not have a negative DNS cache? The version that I tested this on was syslog-ng-3.37.1-1.el7 on RHEL7. ______________________________________________________________________________ Member info: https://lists.balabit.hu/mailman/listinfo/syslog-ng Documentation: http://www.balabit.com/support/documentation/?product=syslog-ng FAQ: http://www.balabit.com/wiki/syslog-ng-faq
