I am observing/suspecting a race condition while starting the lxc, sometime its start correctly, sometimes not, After seeing the log, concluded that not able to create the complete/correct path. because of that not able to start.

I am new to lxc, do not have any idea about it.
I was suspecting that “/sys/fs/cgroup” created by the filesystem. am I correct?
Can someone please explain me the below points:
- what is the creation sequence?
- What could be the reason to not create the correct path?
Or any suggestion to move ahead on this.
Thanks
