We have a proxy server running squid with a good number of clients connected. Sometimes clients just cant browse pages anymore (not all clients, but most). They can ping the proxy, ping to outside servers, resolve dns, and so does the proxy server. I checked CPU (5-10% usage), memory (not swapping), Disk, load, connections, firewall, everything is fine. No errors on systems logs and cache.log. Squid is up and running. Squid FD limit is 4096 but wasnt even near this limit (netstat -na | grep 3128 | wc -l returned around 400 and lsof -nPi | grep squid | wc -l returned around 30) So, on the proxy server, I try "telnet 127.0.0.1 3128".Sometimes it times out, sometimes it connects quickly, sometimes it takes like 5 seconds to connect. I tried a lot of times and this is what keeps happening, most of the time it does not connect. If i run squid -k reconfigure, telnet goes back to normal and people browsing goes back to normal. Has anyone here ever had a problem like this? Any ideas on what might be the cause? -- View this message in context: http://www.nabble.com/Very-strange-squid-problem-tp24410570p24410570.html Sent from the Squid - Users mailing list archive at Nabble.com.
