Sorry if this a double post. Squid version:squid-2.5.STABLE10 O/S: 5.8 Generic_117350-12 sun4u sparc SUNW,Ultra-80 Hi, I'm a sysadmin who has inherited a small cluster of squid servers, the setup is as follows. 4 x Squid Slave Accelerators that accel a master squid. 1 x Master Squid running a custom made redirect script written in perl that accel a Webserver . 1 x Backend Webserver. Each slave is running 4 versions of squid accelerating separate sites. The master runs 4 instances of squid. The farm is constantly under a fair load - roughly half a million hits a day. The setup works fine, however, recently when the master server was taken down for repair, and brought back up again with the same configuration, it failed to serve content for the busiest instance, and every request returned is with a TCP_DENIED 403 error. The following error was reported in the cache.log 2006/03/18 06:04:52| WARNING: Forwarding loop detected for: GET /folder1/subfolder/subfolder/ HTTP/1.0 If-Modified-Since: Sat, 14 Jan 2006 01:44:45 GMT Host: 192.168.0.10 Accept: */* From: googlebot(at)googlebot.com User-Agent: Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) Accept-Encoding: gzip Via: 1.1 slave1.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver), 1.0 master.mydomain.com:80 (webserver/webserver) This has happened previously when the server rebooted, it is likely that the master squid service is getting hammered by all slaves as soon as it is brought back into service, could the fact that it's under such heavy load as soon as it starts up be causing a problem in Squid? I have altered the output to respect privacy of client.
