Hi I am facing the same problem but with different messages, any help on this matter will be highly appreciated. As I am just a beginner at using squid and linux and I am not even sure where to dig for the solution. Is it a squid problem or a kernel problem or some driver problem. Any help will be highly appreciated. I am using the same setup as described above by Mr.Felipe (Bridge+squid+tproxy on an ISP network). I am using squid 3.2.0.8 with kernel 2.6.38-8 on ubuntu. /kernel: [271296.882782] ------------[ cut here ]------------ kernel: [271296.882794] WARNING: at /build/buildd/linux-2.6.38/net/ipv4/tcp_input.c:2964 tcp_fastretrans_alert+0x391/0xba0() kernel: [271296.882800] Hardware name: ProLiant ML110 G6 kernel: [271296.882803] Modules linked in: ebt_redirect ebt_ip ebtable_broute ebtables xt_TPROXY nf_tproxy_core xt_tcpudp xt_socket nf_defrag_ipv4 ip6_tables nf_defrag_ipv6 xt_mark iptable_mangle ip_tables x_tables vesafb bridge stp bpctl_mod lp parport usbhid hid tcp_westwood ahci libahci igb tg3 dca kernel: [271296.882836] Pid: 965, comm: squid Tainted: G W 2.6.38-8-server #42-Ubuntu kernel: [271296.882840] Call Trace: kernel: [271296.882842] <IRQ> [<ffffffff81065d1f>] ? warn_slowpath_common+0x7f/0xc0 kernel: [271296.882855] [<ffffffff81065d7a>] ? warn_slowpath_null+0x1a/0x20 kernel: [271296.882861] [<ffffffff8152ee21>] ? tcp_fastretrans_alert+0x391/0xba0 kernel: [271296.882866] [<ffffffff8152f964>] ? tcp_ack+0x334/0x660 kernel: [271296.882871] [<ffffffff81530bf2>] ? tcp_rcv_established+0x342/0x720 kernel: [271296.882878] [<ffffffff81538901>] ? tcp_v4_do_rcv+0xb1/0x1c0 kernel: [271296.882884] [<ffffffff8153adb6>] ? tcp_v4_rcv+0x646/0x900 kernel: [271296.882891] [<ffffffff81516ef0>] ? ip_local_deliver_finish+0x0/0x280 kernel: [271296.882897] [<ffffffff81516fcd>] ? ip_local_deliver_finish+0xdd/0x280 kernel: [271296.882903] [<ffffffff81517338>] ? ip_local_deliver+0x88/0x90 kernel: [271296.882908] [<ffffffff81516c75>] ? ip_rcv_finish+0x145/0x3c0 kernel: [271296.882913] [<ffffffff8151757c>] ? ip_rcv+0x23c/0x300 kernel: [271296.882919] [<ffffffff8115132e>] ? spin_unlock+0xe/0x20 kernel: [271296.882926] [<ffffffff814e2a23>] ? __netif_receive_skb+0x3e3/0x580 kernel: [271296.882932] [<ffffffff814e36a8>] ? netif_receive_skb+0x58/0x80 kernel: [271296.882938] [<ffffffff814e3810>] ? napi_skb_finish+0x50/0x70 kernel: [271296.882944] [<ffffffff814e3d85>] ? napi_gro_receive+0xb5/0xc0 kernel: [271296.882954] [<ffffffffa0040e24>] ? igb_clean_rx_irq_adv+0x524/0x660 [igb] kernel: [271296.882961] [<ffffffff8100e982>] ? handle_irq+0x22/0x40 kernel: [271296.882969] [<ffffffffa0040fd0>] ? igb_poll+0x70/0x150 [igb] kernel: [271296.882975] [<ffffffff814e3f88>] ? net_rx_action+0x128/0x270 kernel: [271296.882981] [<ffffffff8106d398>] ? __do_softirq+0xa8/0x1c0 kernel: [271296.882986] [<ffffffff8100cedc>] ? call_softirq+0x1c/0x30 kernel: [271296.882991] [<ffffffff8100ea05>] ? do_softirq+0x65/0xa0 kernel: [271296.882995] [<ffffffff8106d5b5>] ? irq_exit+0x85/0x90 kernel: [271296.883001] [<ffffffff815df986>] ? do_IRQ+0x66/0xe0 kernel: [271296.883007] [<ffffffff815d7cd3>] ? ret_from_intr+0x0/0x15 kernel: [271296.883010] <EOI> [<ffffffff813355da>] ? intel_idle+0xca/0x120 kernel: [271296.883020] [<ffffffff813355b9>] ? intel_idle+0xa9/0x120 kernel: [271296.883027] [<ffffffff814b628a>] ? cpuidle_idle_call+0xaa/0x1b0 kernel: [271296.883034] [<ffffffff8100a266>] ? cpu_idle+0xa6/0xf0 kernel: [271296.883040] [<ffffffff815ba8c5>] ? rest_init+0x75/0x80 kernel: [271296.883046] [<ffffffff81ae1c8b>] ? start_kernel+0x3f5/0x400 kernel: [271296.883051] [<ffffffff81ae1388>] ? x86_64_start_reservations+0x132/0x136 kernel: [271296.883056] [<ffffffff81ae1253>] ? zap_identity_mappings+0x3e/0x41 kernel: [271296.883061] [<ffffffff81ae1458>] ? x86_64_start_kernel+0xcc/0xdb kernel: [271296.883065] ---[ end trace 44593438a59a953b ]--- / -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/squid-2-7Stable8-hangup-tp2282741p3904068.html Sent from the Squid - Users mailing list archive at Nabble.com.
