Mmm.. it seems that I might need a bit more info to diagnose the problem. Could you also post the output of the following command: grep ^ /var/dnscache/root/servers/* > the two log tails were started at the same time, but the activity was=20 > seen in the tinydns log first, then the dnscache. Well, those log snippets do not seem to cover the same time interval. Running them through the tai64nlocal utility shows that the tinydns log entries are from 13:04:29 to 13:04:59, while the dnscache ones start at 13:05:39. Are there any dnscache log entries for 13:03 or 13:04?
