apport information ** Description changed:
Some of our nova compute hosts regularly freeze, sometimes for a few hours, with kern.log getting spammed with: block nbdX: Attempted send on closed socket and a few "CPU soft lockup" messages (see attached log). This clears up when the queue gets cleared, eg : block nbdX: queue cleared trusty hosts with kernel version 3.19.0-30-generic. + --- + AlsaDevices: + total 0 + crw-rw---- 1 root audio 116, 1 Nov 24 12:23 seq + crw-rw---- 1 root audio 116, 33 Nov 24 12:23 timer + AplayDevices: Error: [Errno 2] No such file or directory + ApportVersion: 2.14.1-0ubuntu3.19 + 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: + DistroRelease: Ubuntu 14.04 + IwConfig: Error: [Errno 2] No such file or directory + MachineType: HP ProLiant DL385 G7 + Package: linux (not installed) + PciMultimedia: + + ProcEnviron: + TERM=screen-256color + PATH=(custom, no user) + LANG=en_US.UTF-8 + SHELL=/bin/bash + ProcFB: 0 radeondrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.19.0-36-generic root=UUID=13289ac9-8dc9-4feb-b6bd-ca7db66b21d6 ro console=tty0 console=ttyS1,38400 nosplash crashkernel=384M-:512M nox2apic intremap=off + ProcVersionSignature: Ubuntu 3.19.0-36.41~14.04.1hf00090138v20151122b1-generic 3.19.8-ckt9 + RelatedPackageVersions: + linux-restricted-modules-3.19.0-36-generic N/A + linux-backports-modules-3.19.0-36-generic N/A + linux-firmware 1.127.18 + RfKill: Error: [Errno 2] No such file or directory + Tags: trusty uec-images + Uname: Linux 3.19.0-36-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: + + _MarkForUpload: True + dmi.bios.date: 02/02/2014 + dmi.bios.vendor: HP + dmi.bios.version: A18 + dmi.chassis.type: 23 + dmi.chassis.vendor: HP + dmi.modalias: dmi:bvnHP:bvrA18:bd02/02/2014:svnHP:pnProLiantDL385G7:pvr:cvnHP:ct23:cvr: + dmi.product.name: ProLiant DL385 G7 + dmi.sys.vendor: HP ** Attachment added: "BootDmesg.txt" https://bugs.launchpad.net/bugs/1505564/+attachment/4524649/+files/BootDmesg.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1505564 Title: Soft lockup with "block nbdX: Attempted send on closed socket" spam Status in linux package in Ubuntu: In Progress Bug description: Some of our nova compute hosts regularly freeze, sometimes for a few hours, with kern.log getting spammed with: block nbdX: Attempted send on closed socket and a few "CPU soft lockup" messages (see attached log).
