Error running in LXC container: **libbpf: Failed to bump RLIMIT_MEMLOCK (err = -1), you might need to do it explicitly!**

Hi, congratulations for sshlog 💯
I'm running sshlog in differents environments properly but I have a problem with sshlog when running inside a LXC container with PROXMOX. (Privileged or unprivileged, nesting or without nesting, with same error result)
I attach the logs below, It's a Debian 12. Thanks in advance and apologize me because it isn't a sshlog issue specific.

Finally I reinstall the server in KVM instead a LXC container.
