- Checkout access.log for those requests which are failing, if the
DNS problem is apparent.
- Also ,review cache.log completely, watchout for any errors related to
DNS or other stuff.
- If nslookup fails to, you are likely to have system problems.
The dnsservers are determined in /etc/resolv.conf.
Use more then one dns server.
