This configuration parameter specifies the amount of time to wait, in seconds, when DNS is down, before triggering a DNS server sweep to see if any DNS servers are alive.

If the current DNS server times out on a request (does not respond within the interval and number of retries specified by dns.tcp.timeout or dns.udp.timeouts), the agent attempts to acquire another DNS server. If it fails to find a live server, DNS is considered down and the agent waits for the interval specified by this parameter, dns.dead.resweep.interval, before attempting to acquire another DNS server.

The default is 60 seconds.

The parameter value must be a positive integer. For example:

dns.dead.resweep.interval: 60
