The VM froze because of the Kernel bug appended as a text file. I had to hard reset it. I am running Ubuntu 14.04.2 Kernel 3.16.0-34-generic with libapache2-mod-apparmor 2.8.95~2430-0ubuntu5.1 and apache 2.4.7-1ubuntu4.4 (mpm_prefork). Unfortunately I am unable to reproduce the bug at will. This is a serious problem for high availability VMs. Looking at the trace, I assume this is a bug in AppArmor. --- AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 May 15 14:13 seq crw-rw---- 1 root audio 116, 33 May 15 14:13 timer AplayDevices: Error: [Errno 2] No such file or directory ApportVersion: 2.14.1-0ubuntu3.10 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 HibernationDevice: RESUME=UUID=69e1aff7-c3d1-4bf4-8685-bd3fc2942f60 InstallationDate: Installed on 2015-03-25 (61 days ago) InstallationMedia: Ubuntu-Server 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) IwConfig: eth0 no wireless extensions. lo no wireless extensions.
