These directories are never cleaned up. mkdocs should handle SIGTERM and/or cleanup leftover /tmp directories on startup.\n\n#### My setup\nI run mkdocs inside a docker container [see the [mkdocs-material project](https://github.com/squidfunk/mkdocs-material)]. By default, the docker starts \"mkdocs serve\".\n\nThe issue occurs when the container is stopped. To stop a container, docker [sends SIGTERM](https://docs.docker.com/reference/cli/docker/container/stop/#description) to the main process and waits for the signal to be handled. In the case of mkdocs-material, the main process is tini, but tini already [forwards signals](https://github.com/krallin/tini/blob/master/src/tini.c#L526) to the child mkdocs process. To confirm the behaviour, I've also sent SIGTERM directly to mkdocs [eg. `kill -s TERM \u003cmkdocs-pid>`] and mkdocs still fails to clean up /tmp directories.\n","author":{"url":"https://github.com/toddke","@type":"Person","name":"toddke"},"datePublished":"2025-01-17T00:34:16Z","url":"https://github.com/mkdocs/mkdocs/issues/3905"}
