Well I installed that 2 patches on my 3 hosts, since that day I can run backups on nfs storage like a charm.
BUT already a third time it happens that 1 host cant quit processes and start more and more until it stuck.
I can't stop container or migrate them, just got a timeout. I even can't reboot via shell, I have to make it via IPMI.
As I said it happens since that patch and only on 1 host, to investigate I moved alle container except 2 to another host.
Syslog says just before reboot:
