Folks at colocation site provided me with the following "screenshot": http://miha.krneki.org/netfilter/kernelpanic.jpg I'm not sure whether this is related with netfilter/iptables, tg3 or something else, but the screenshot is full of netfilter messagess, so I tried this list first. Funny thing is that /proc/sys/kernel/panic was set to 60 seconds, yet the machine did not reboot itself after the crash and colocation people said machine was not responding to keyboard, so they could not provide the whole trace. Another interesting thing - machine is heavily loaded (apache+php+mysql) - pushing around 35-45mbit/s througout the whole day. After midnight utilization gets very low and yet all 3 crashes occured at around 2AM local time. There are no cron scripts at that time that would cause any cpu/network hammering, system is virtually idle. Server is Dual Opteron 250 with 4gb ECC RAM and Adaptec 2015S SCSI controller (2x RAID1). At the time of crash, system was using: OS: (32bit) slackware-based with: glibc 2.3.6 (NPTL), gcc 3.3.6, iptables 1.3.4 (upgraded to 1.3.5 after crash) kernel 2.6.17.8 with the following patches: - grsecurity 2.1.9 (200608012135) - dpt_i2o-2.5.0-2426 driver from adaptec SMP and PAE are enabled, config file is located at: http://miha.krneki.org/netfilter/config-2.6.17.8+d1 If anyone has any clue, don't hesitate to contact me.
