Creating a Tokio runtime panics on older kernels (e.g. CentOS 5) — possible cgroup issue

[seventeenman]

Description

When trying to create a Tokio runtime on a machine running CentOS 5 (with an older Linux kernel), the program panics at runtime. The panic seems to be related to missing cgroup support in the kernel.
Is there any known temporary workaround or recommended configuration that allows Tokio to run on older Linux systems?

Environment

• Tokio version: 1.45
• OS: CentOS 5 (kernel 2.6.18)

Reproduction

let rt = Runtime::new()
    .unwrap();

It would be better getting the panic message. 🤔

That Linux kernel version is from 2006. It's not supported. In fact, even the Rust language itself requires a newer kernel version.
