I have a problem with Linux crashing every few days on a box with fairly large network traffic (~600-800 Mbit/s traffic, >20000-45000 connections in "netstat -tna | wc -l"). The box serves as a proxy. I tried updating to every new 2.6.35.x kernel, but it didn't help. Previously, it was running 2.6.32.x, but was showing similar behaviour. The logs don't capture much, I have some screenshots and such snippet: May 8 10:38:15 TRUE-SC02 kernel: [610430.540540] BUG: unable to handle kernel NULL pointer dereference at (null) May 8 10:38:15 TRUE-SC02 kernel: [610430.540577] IP: [<ffffffff81361cae>] dev_queue_xmit+0x1e3/0x441 May 8 10:38:15 TRUE-SC02 kernel: [610430.540606] PGD 813f8a067 PUD 813f8b067 PMD 0 May 8 10:38:15 TRUE-SC02 kernel: [610430.540637] Oops: 0000 [#1] SMP May 8 10:38:15 TRUE-SC02 kernel: [610430.540658] last sysfs file: /sys/devices/system/cpu/cpu7/cache/index2/shared_cpu_map May 8 10:38:15 TRUE-SC02 kernel: [610430.540686] CPU 4 The screenshots: http://virtall.com/files/temp/IMG00066-20110420-0956.jpg http://virtall.com/files/temp/IMG00067-20110420-0957.jpg 07:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01) Does it look like anything familiar? -- Tomasz Chmielewski http://wpkg.org -- To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
