[squid-users] The requested URL could not be retrieved

Dear all,
I had squid 2.5 running on a linux 9.0 box but recently, every morning, I
would not be able to access the internet via the proxy server until I
restart the server. The error message was :

The following error was encountered :
      Unable to determine IP address from hist name for yahoo.com

The dnsserver returned :
      Server Failure : The name server was unable to process this query.

This means that :
The cache was not able to resolve the hostname presented in the URL.
Check if the address is correct.

Any idea why ?
