Slow DNS lookups when DNS does not respond

Hi all, I have stunnel setup on a Linux box and I am experiencing very slow DNS lookup times when DNS does not respond. On this same system, anything that results in a DNS lookup (e.g. ping, ...) takes about 20 seconds before it times out and fails. However with stunnel (and a single service configured) the lookup takes more than 1 minute (approx 80 seconds). Is there any way to configure this? Thank you, Guillermo Rodriguez Garcia [email protected]
