[squid-users] log_fqdn

I have set log_fqdn option to "on" and have now problem which I cannot
solve. My log seems to work fine but sometimes records with unresolved
ip's appear instead of domain names. I have bind server functioning on
the localhost, so there should be minimum delay. I have even updated
squid to version 2.5-STABLE2 (had 2.4-STABLE6 or something). Someone
said in this list that there can be problems if dns responses are too
slow. But 1) dns is local and 2) named maintains the zone and it's
reverse for clients.
