I have compiled and installed squid 3.3.8. I have about 160Mbps bandwidth and about 18000 http request per minute. The problem is that as soon as I redirect traffic to squid, its cpu usage reaches 100% and it hangs and even "squidclient" will not work. What is weird is that when I remove traffic from squid, CPU usage does not go down immediately, but with a delay of about 2 or 3 minutes! While in version 3.1.19(which previously I was using), as soon as I remove traffic from squid, its cpu usage goes down. By the way in 3.1.19, CPU usage never exceeded 30%. When I debug , I see some lines saying: WARNING! Your cache is running out of filedescriptors I don't know this is the cause or not. But I've already compiled squid with 65536 filedescriptors I have disabled disk swap for testing, but the problem yet exists. Any help is appreciated I have attached my compile options and config _______________________________________ #squid -v Squid Cache: Version 3.3.8 configure options: '--prefix=/usr/local/squid' '--build=x86_64-linux-gnu' '--enable-storeio=ufs,aufs,diskd' '--enable-follow-x-forwarded-for' '--with-filedescriptors=65536' '--with-large-files' '--with-default-user=proxy' '--enable-linux-netfilter' 'build_alias=x86_64-linux-gnu' --enable-ltdl-convenience ###config:#### acl localnet src 10.0.0.0/8 # RFC1918 possible internal network acl localnet src 172.16.0.0/12 # RFC1918 possible internal network acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT shutdown_lifetime 3 second wccp2_router 172.22.122.254 wccp_version 2 wccp2_rebuild_wait on wccp2_forwarding_method 2 wccp2_return_method 2 wccp2_assignment_method 2 # wccp2_service standard 0 wccp2_service dynamic 80 wccp2_service dynamic 90 wccp2_service_info 80 protocol=tcp flags=src_ip_hash priority=240 ports=80 wccp2_service_info 90 protocol=tcp flags=dst_ip_hash,ports_source priority=240 ports=80 http_port 3129 tproxy qos_flows local-hit=0x18 cache_mem 2000 MB maximum_object_size_in_memory 10 MB access_log none snmp_port 3401 acl snmppublic snmp_community golabi snmp_access allow snmppublic trusted http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localhost manager http_access deny manager http_access allow localnet http_access allow localhost http_access deny all http_port 3128 coredump_dir /usr/local/squid/var/cache/squid refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320
