</span>It's unfortunately a known issue with lxcfs (and one that is based on a<br>
kernel limitation so unlikely to be resolved very soon).<br>
<br>
Restarting lxcfs (by an update or a crash) causes any container using it<br>
to return empty files instead of the lxcfs files.<br>
<br>
The only fix for this issue is to restart all your containers whenever<br>
lxcfs is restarted.<br>
