Anyway the fix is simple. If that's all it was, seems to do the trick: named -V BIND 9.11.1 running on Linux x86_64 4.10.10-2.ga78ebd0-default #1 SMP PREEMPT Wed ... compiled by GCC 6.3.1 20170331 [gcc-6-branch revision 246609] compiled with OpenSSL version: OpenSSL 1.1.0e 16 Feb 2017 linked to OpenSSL version: OpenSSL 1.1.0e 16 Feb 2017 ... thanks!
