unbound continually stopping/starting



  • My DNS resolver turned itself off suddenly for no reason so I checked the DNS resolver log and found that unbound seems to be stopping and starting continually.
    Is this normal or do I have an issue? I can't see any other issue and it seems to be working after I restarted unbound service.
    I do have pfBlocker NG installed but updates are set for 1 hour.

  • Check other logs, like DHCP.

    And check this :

    if this option is checked, then for every new lease, the Resolver will get restarted.
