apport information ** Tags added: apport-collected ec2-images trusty
** Description changed: Kernel oops occurs randomly every now and then, seemingly when running memory-intensive processes (so far, it happened to me when using bowtie2 or STAR). Running Ubuntu 14.04 LTS on AWS EC2 instances (m4.* and c4.* family classes). After the error occurs, the server stays accessible through SSH, but the commands w, htop, ps (and maybe others) seem to hang, while commands like ls, cd, top and others keep working. Whatever process was running and (probably) caused the crash seems to go into a sleeping mode. Rebooting (sudo reboot) makes the instance refuse all connections (more than an hour after initiating the reboot). Stopping the (AWS EC2) instance and starting again makes the instance function normally again. - Restarting the task that was running when the instance crashed on the - newly (re)started instance usually works with no more problems. + Restarting the task that was running when the instance crashed on the newly (re)started instance usually works with no more problems. + --- + AlsaDevices: + total 0 + crw-rw---- 1 root audio 116, 1 Jan 23 12:49 seq + crw-rw---- 1 root audio 116, 33 Jan 23 12:49 timer + AplayDevices: Error: [Errno 2] No such file or directory + ApportVersion: 2.14.1-0ubuntu3.29 + Architecture: amd64 + ArecordDevices: Error: [Errno 2] No such file or directory + AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: + CRDA: Error: [Errno 2] No such file or directory + DistroRelease: Ubuntu 14.04 + Ec2AMI: ami-4473183b + Ec2AMIManifest: (unknown) + Ec2AvailabilityZone: us-east-1c + Ec2InstanceType: m4.16xlarge + Ec2Kernel: unavailable + Ec2Ramdisk: unavailable + IwConfig: Error: [Errno 2] No such file or directory + Lsusb: Error: command ['lsusb'] failed with exit code 1: unable to initialize libusb: -99 + MachineType: Xen HVM domU + Package: linux (not installed) + PciMultimedia: + + ProcEnviron: + TERM=xterm + PATH=(custom, no user) + XDG_RUNTIME_DIR=<set> + LANG=en_US.UTF-8 + SHELL=/bin/bash + ProcFB: + + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-164-generic root=UUID=d4f2aafc-946a-4514-930d-4c45e676f198 ro console=tty1 console=ttyS0 + ProcVersionSignature: Ubuntu 3.13.0-164.214-generic 3.13.11-ckt39 + RelatedPackageVersions: + linux-restricted-modules-3.13.0-164-generic N/A + linux-backports-modules-3.13.0-164-generic N/A + linux-firmware N/A + RfKill: Error: [Errno 2] No such file or directory + Tags: trusty ec2-images + Uname: Linux 3.13.0-164-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: sudo + WifiSyslog: + + _MarkForUpload: True + dmi.bios.date: 08/24/2006 + dmi.bios.vendor: Xen + dmi.bios.version: 4.2.amazon + dmi.chassis.type: 1 + dmi.chassis.vendor: Xen + dmi.modalias: dmi:bvnXen:bvr4.2.amazon:bd08/24/2006:svnXen:pnHVMdomU:pvr4.2.amazon:cvnXen:ct1:cvr: + dmi.product.name: HVM domU + dmi.product.version: 4.2.amazon + dmi.sys.vendor: Xen ** Attachment added: "BootDmesg.txt" https://bugs.launchpad.net/bugs/1813018/+attachment/5231751/+files/BootDmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1813018 Title: Kernel Oops - unable to handle kernel paging request; RIP is at wait_migrate_huge_page+0x51/0x70 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813018/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
