Hi, using local_unbound on FreeBSD 11.3 I have the problem that an occasional SERVFAIL is cached for several minutes (not sure about the exact length of time but something like 5 to 15 minutes). Is it possible to reduce this to something like 10 seconds? I did set cache-max-negative-ttl but that apparently only sets the ttl for caching NXDOMAIN. Wolfgang
