Could you try to run a memtest on your host and check your other hardware for fault behaviour? Could you try to reinstall the qemu and the kernel package?

 

[tghd]

Memtest and Hardware are fine. Since the problem was with lxc (not qemu), i first tried to reinstall the lxc related packages:

apt reinstall pve-lxc-syscalld lxcfs lxc-pve

which solved the issue. However thanks for pointing in the right direction.

 

[dakralex]

Great that it pointed you in the right direction!
