Support Central: KB #5039: ‘set holddown’ command blocking all recursive queries
The 'set holddown' command blocking all recursive queries
Infoblox Grid running DNS service with global forwarders and 'set holddown' and forward-only clause enabled
All versions of NIOS
The 'set holddown' command cannot distinguish between a server or a forwarder and for this reason, all configurations are treated the same. Hence, all recursive queries may get 'held down'
Disable the 'set holddown' command and instead use 'fetches-per-server' and 'fetches-per-zone' commands.
