Since around 2019-07-23, lxcfs segfaults randomly on Ubuntu 18.04
servers with LXD from snap:
lxcfs[1424]: segfault at 0 ip 00007f518f5e4326 sp 00007f519da1f9a0 error
4 in liblxcfs.so[7f518f5d8000+1a000]
As a result, containers malfunction. If a container is stopped, then
started again - everything works well, however - after a few hours, it
happens again.
root@uni01:~# free
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"
root@uni01:~# uptime

Is it a known issue? I'm observing it on around 10 servers.
