lxc-start --version
3.0.4
I am using 3.0.4 version lxc, I am seeing below problem sometimes, I mean it is not reproducible every time.
As per the log, it is showing “/sys/fs/cgroup/memory/lxc.payload/mylxcpath” is created but when it is trying to set the limit, it is failing.

Please suggest where to look for this.
