## Expected Behaviour

`make audit` should succeed

## Steps to resolve

Two known soludions:
1. Get rust-psutil to merge [this pull PR 93](https://github.com/rust-psutil/rust-psutil/pull/93) and then change common/eth2/Cargo.toml to use the latest psutil.
2. Create a local change that fixes it, such as #2697
