Hi guys,

we are facing an issue with one node for some days now.
The node itself is listed green in proxmox, all services running:
http://prntscr.com/jvni6z

All CTs are running and accessable fine via SSH, also summary in proxmox of these CTs work fine. No issues so far. Also the proxmox API give status "ONLINE" back.
But: All CTs show a grey questionmark:
http://prntscr.com/jvnie8

Any ideas to debug it further?
It only affects CTs on one node. All other nodes CTs are showing a green icon.
 
you could try to to restart the pvestatd on that node
 
systemctl status pvestatd shows this:

When I restart these mentioned CTs it is fixed for a while but happens again after some minutes/hours.
