That was almost the same problem I had. I had squid running for months 
on this particular Linux box until suddenly it stoped and I check my
cache.log and have similar error message that cannot execu dnsserver.
Since then I have re-install and even upgrade to squid 2.X but still 
have the same problem. 
Does anyone know what exactly happens when dnsserver fail?
