Looks like your problem is caused by the failing "pinger". Which means, there is an "--enable-icmp" in your config options, when building squid. So another possibillity would be to remove this config option. AFAIK in your situation, the "pinger" would only be an advantage (or even necessary), in case of alternatives for your upstream proxy, to detect the closest one. But as your squid has no choice, you should be able to disable it completely. Or to give proper rights to the "pinger", although redundant. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Probs-with-squid-3-4-4-and-cache-peer-parent-tp4666557p4666580.html Sent from the Squid - Users mailing list archive at Nabble.com.
