[squid-users] Problems with squidclient

Hi. I'm trying to get basic squid info by issuing 'squidclient -p 8080 mgr:info'. Port 8080 is where our squid is listening to connections. All clients works fine through the squid. But squidclient return http response (lets say mydomain.com is my domain): ERROR The requested URL could not be re

[squid-users] Frequent cache rebuilding

Hi. What are the reasons of squid rebuilding it's cache? Sometimes after startup sometimes during work it starts to rebuild cache. I see it in cahce.log: 2009/01/16 09:30:24| Starting Squid Cache version 2.6.STABLE6 for x86_64-redhat-linux-gnu... 2009/01/16 09:30:24| Process ID 2625 2009/01/16 0

Re: [squid-users] squid caching report

Damn! I changed squid cache directory to local partition and still see the same problem. # vmstat 2 procs ---memory-- ---swap-- -io --system-- -cpu-- r b swpd free buff cache si sobibo in cs us sy id wa st 1 0 0 3148784 297840 206828

For some unknown reason squid stopped using CPU even when I returned cache to NFS partition: procs ---memory-- ---swap-- -io --system-- -cpu-- r b swpd free buff cache si sobibo in cs us sy id wa st 2 0 96 2665972 119112 5137560
