High RAM usage in WSL2 - Githubissues

I am using VSCode and the isort extension v2022.2.0 (isort=5.10.1)

My pyproject.toml contains:

[tool.isort]
profile = "black"
line_length = 88
multi_line_output = 3
include_trailing_comma = true
skip_gitignore = true
skip = ["notebooks", "resources", "data"]
known_third_party = ["wandb", "hydra"]

I get really high RAM usage for the format_server.py. I tried increasing the WSL2 memory, but after a while the isort format server allocates all free memory on my ubuntu subsystem, until the swap is full and my wsl freezes.

The logs contain

Formatter Name: isort
Formatter Module: isort
CWD Format Server: /home/flo/dev/redacted
sys.path used to run Formatter:

        "severity": {},
        "path": [],
        "interpreter": [
            "/home/flo/dev/redacted/.venv/bin/python"
        ]
    }
]

I get a few exceptions based on #isort: skip_file comments:
