This configuration parameter specifies the amount of time, in seconds, to wait before re-sending a TCP request, when there is no response from the current DNS server. If the current server does not respond to this request, it is considered down, which triggers a sweep to acquire a new server as specified by the dns.sweep.pattern parameter. The new server becomes the selected server (it is cached in memory and its address is put in kset.dns.server), and it attempts to handle the DNS request.

The default value is 1 second. You may specify only one TCP retry.

Specify a positive integer; for example:

dns.tcp.timeout: 1

This parameter specifies the timeout values for TCP requests. Use dns.udp.timeouts to specify timeout values for UDP requests.
