[lxc-users] Instabilties

Thu Aug 30 12:14:56 UTC 2018

When I start a new clean lxd instance, I can lxd init, launch first.
Then I try to work, it works, I success import from other lxd.
At some point, some lxc command fails, such as lxc copy (local).
Then nothing works more, any lxc command get soxket error.
If I reboot, "lxc ls" gives the same error and the messages that I have sent.
I hope I am clear...

 I have a few questions:

1) Does the failure happen when you start with a fresh lxd instance?

2) If the answer to 1) is "no", is there are repeatable process that you
  have that brings you from a fresh lxd instance to the point were it
  crashes with the failure you pasted?

3) Regardless of the answers to 1) and 2), does the failure happen
  consistently? I.e. does it happen every time you run "lxc ls".
