Hey, The configuration listet above, runs longer 1 year without an probs. Now we get the Squid Message: Timeout - DNS Error. first step i tried: dig google.de from the squid maschine. No probs. i saw in the cache.log that all url_rewrite_children are busy, so i screwd em up from 8 to 16. Okey one Day later: DNS Error, and at this Time, no prob with the url_rewrite_children. now i added some dns Server and the google dns Server (8.8.8.8) which should be up, and what i recieved today :/ dns Error. After squid restart all works fine, no probles comes up in the logs (in all logs) but after a day, the messaged blow up again. now i added dns_nameserver in the squid.conf but no idea any more? thanks for spending time on this. --- freenetMail - Der zuverlÃssige E-Mail-Dienst von freenet.de Jetzt http://mail.freenet.de/produkte/basic/index.html?pid=10111947018 mit 1 GB Speicher und Profi-Spamschutz sichern!
