The consequence on lxc containers :

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"

 /proc/cpuinfo is not accessible: Transport endpoint is not connected

If i umount /proc then remount it inside lxc container, the errors disappear but I would like to know the origin of the problem and know if we can correct it?

Plus, the problem happens randomly.
