Hi...
I updated a Proxmox VE server with last version 8.
But suddenly ifreload -a doesn't work leading to a fault network frr
Here the error:
ifreload -a

Received signal 11

this signal (11) is a "SIGSEGV" which means there was a segmentation fault somewhere. I'd guess it's either some corrupted file (you could check this with the 'debsums' package+command) or faulty hardware (like e.g. faulty memory)

since it happened after an upgrade i'd assume the first option
