Public bug reported: Hi,
lxcfs crashed earlier today requiring us to restart a bunch of LXC containers. I'm not able to upload using apport-bug but here's the attached crash report. I commented on https://github.com/lxc/lxcfs/issues/73#issuecomment-445598111 and repeating what I said here: | Dec 8 06:25:03 orlo kernel: [25247258.665022] lxcfs[3871]: segfault at 0 ip 00007fe70ae4e3b2 sp 00007fe70884fb70 error 4 in liblxcfs.so[7fe70ae46000+f000] | Dec 8 06:25:09 orlo systemd[1]: lxcfs.service: Main process exited, code=killed, status=11/SEGV | Dec 8 06:25:09 orlo systemd[1]: lxcfs.service: Unit entered failed state. | Dec 8 06:25:09 orlo systemd[1]: lxcfs.service: Failed with result 'signal'. | Dec 8 06:25:10 orlo systemd[1]: lxcfs.service: Service hold-off time over, scheduling restart. | Dec 8 06:25:10 orlo lxcfs[10839]: hierarchies: | Dec 8 06:25:10 orlo lxcfs[10839]: 0: fd: 5: perf_event | Dec 8 06:25:10 orlo lxcfs[10839]: 1: fd: 6: blkio | Dec 8 06:25:10 orlo lxcfs[10839]: 2: fd: 7: freezer | Dec 8 06:25:10 orlo lxcfs[10839]: 3: fd: 8: devices | Dec 8 06:25:10 orlo lxcfs[10839]: 4: fd: 9: cpuset | Dec 8 06:25:10 orlo lxcfs[10839]: 5: fd: 10: cpu,cpuacct | Dec 8 06:25:10 orlo lxcfs[10839]: 6: fd: 11: pids | Dec 8 06:25:10 orlo lxcfs[10839]: 7: fd: 12: memory | Dec 8 06:25:10 orlo lxcfs[10839]: 8: fd: 13: net_cls,net_prio | Dec 8 06:25:10 orlo lxcfs[10839]: 9: fd: 14: hugetlb | Dec 8 06:25:10 orlo lxcfs[10839]: 10: fd: 15: name=systemd So now after restarting it, the containers are showing this: | Error: /proc must be mounted | To mount /proc at boot you need an /etc/fstab line like: | proc /proc proc defaults | In the meantime, run "mount proc /proc -t proc" Package version: | ubuntu@orlo:~$ cfs | lxcfs: | Installed: 2.0.8-0ubuntu1~16.04.2 | Candidate: 2.0.8-0ubuntu1~16.04.2 | Version table: | 3.0.2-0ubuntu1~16.04.1 100 | 100 http://archive.ubuntu.com/ubuntu xenial-backports/main amd64 Packages | *** 2.0.8-0ubuntu1~16.04.2 500 | 500 http://archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages | 100 /var/lib/dpkg/status | 2.0.0-0ubuntu2 500 | 500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages ** Affects: lxcfs (Ubuntu) Importance: Undecided Status: New ** Attachment added: "_usr_bin_lxcfs.0.crash" https://bugs.launchpad.net/bugs/1807628/+attachment/5220767/+files/_usr_bin_lxcfs.0.crash ** Description changed: Hi, lxcfs crashed earlier today requiring us to restart a bunch of LXC containers.
