I was working on this system with SquirrelMail and Sendmail. and Suddenly I got Kernel Panic.. I know I cant save what I was doing but maybe somebody can tell me why this happened so I can assure it wont happen again.. The Registers Values: eax: E0C415A0 ebx: 00000004 ecx: E0C40F04 edx: CC39BF6C esi: CC39BF6C edi: C017C9B8 ebp: 09FF0000 esp: CC39BF38 The Stack: DC823140 D7B6BD80 C017C9B8 09FF0000 C017CA8D A1FE3000 DC823140 D7B6DBA0 00000000 (7x) DC823140 A1FE3000 C017C9B8 09FF0000 C0161096 CC39BFA4 DC823140 FFFFFFF7 A1Fe3000 Call Trace: syscall_call+0x7/0xB I run Gentoo on this box and its been on for 18 days.. What can cause such a Fatal Crash? Reproducible: Didn't try Actual Results: I had to reboot
Post emerge --info as well as the involved versions please
Some relevant informasion would be kernel version, drivers used, output from lspci, filesystems used. Kernel panics are not something that should happen, and there is a bit hard to tell what you must to in order to avoid them, since we don't know why it crashed for you. (kernel panic = a crash in the kernel, or simular)
Ah, ok well the Gentoo Systems are OpenVZ systems with as Mother System Debian (Stable). So, well this might also be a Debian problem. But I guess its Gentoo since I was working with that. But ok the Gentoo System is a Shared OpenVZ Linux Kernel. The Sendmail Server has the following info: Web/Mail_Server / # emerge --info Portage 2.1.2.2 (default-linux/x86/2007.0, gcc-4.1.1, glibc-2.5-r0, 2.6.18-1-openvz i686) ================================================================= System uname: 2.6.18-1-openvz i686 Intel(R) Celeron(R) CPU 2.40GHz Gentoo Base System release 1.12.9 Timestamp of tree: Thu, 22 Nov 2007 13:00:01 +0000 app-shells/bash: 3.1_p17 dev-lang/python: 2.4.3-r4 dev-python/pycrypto: 2.0.1-r5 sys-apps/baselayout: 1.12.9 sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.61 sys-devel/automake: 1.10 sys-devel/binutils: 2.16.1-r3 sys-devel/gcc-config: 1.3.14 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.17-r2 ACCEPT_KEYWORDS="x86" CBUILD="i486-pc-linux-gnu" CFLAGS="-O2 -mtune=i686 -pipe" CHOST="i486-pc-linux-gnu" CONFIG_PROTECT="/etc /sbin/rc" CONFIG_PROTECT_MASK="/etc/env.d /etc/gconf /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/terminfo" CXXFLAGS="-O2 -mtune=i686 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="distlocks metadata-transfer sandbox sfperms strict" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages --filter=H_**/files/digest-*" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="acl apache2 berkdb bitmap-fonts cli cracklib crypt cups dri fortran gdbm gpm iconv ipv6 isdnlog midi mudflap ncurses nls nptl nptlonly openmp pam pcre perl php pppd python readline reflection session spl ssl tcpd truetype-fonts type1-fonts unicode x86 xml xorg zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1 emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mulaw multi null plug rate route share shm softvol" ELIBC="glibc" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" USERLAND="GNU" VIDEO_CARDS="apm ark chips cirrus cyrix dummy fbdev glint i128 i740 i810 imstt mach64 mga neomagic nsc nv r128 radeon rendition s3 s3virge savage siliconmotion sis sisusb tdfx tga trident tseng v4l vesa vga via vmware voodoo" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, LINGUAS, MAKEOPTS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY Web/Mail_Server / # uname -a Linux Web/Mail_Server 2.6.18-1-openvz #4 SMP Mon Dec 17 13:58:18 EST 2007 i686 Intel(R) Celeron(R) CPU 2.40GHz GenuineIntel GNU/Linux Web/Mail_Server / # cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 3 model name : Intel(R) Celeron(R) CPU 2.40GHz stepping : 4 cpu MHz : 2405.658 cache size : 256 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe constant_tsc up pni monitor ds_cpl cid xtpr bogomips : 4815.01 Web/Mail_Server / # lspci -bash: lspci: command not found <- I forgot what Package lspci was in..

But I do not know how to Analyze this and how to fix this error (well so It will never happen again) since this system is now still in Development Stage. But if it gets used and it will Crash my Customers will get REALLY mad. (Rich People who dont know shit about Computers and are scared of Virii) Anyhow thats why I did post this since maybe can analyze this and make sure I (and the Gentoo community) will never get this Flaw again. And maybe its a random Code I did send to Sendmail without knowing it that caused a Remote Kernel Crash.. Well I hope that my post did help the Gentoo community ;) Cheers, Robin
