This seems odd - and might indicate an issue with the installed version running on your System - please post:

pveversion -v
lsmod

Dear Stoiko,
I went through restart pve server to repair this issue.
Thanks.

this error happens commonly after kernel upgrades when you forget to reboot

always do a reboot after kernel upgrades!!
