I now see on my node:

kernel: CT#402 reached the limit on mounts.

 

So think that is the problem.

I see a old toppic onlin https://forum.openvz.org/index.php?t=rview 
<https://forum.openvz.org/index.php?t=rview&th=12902&goto=52002> 
&th=12902&goto=52002

Any idee if that is the solution that is needed today?
