## Acceptance criteria
* **AC1:** **AC1**: gru logs don't contain these unknown error messages
## Suggestions
* Try changing the working directory before invoking code from Archive::Extract
* As desired artifically trigger the problem as mentioned in #123649#note-15
* Check comments for reproducing the issue in production
* Could it be multi-processes trying to access working with the same directories?
* Could it be a system owned tmpfile cleanup?
* Optional: Consider ensuring we have a proper log level reported, e.g. "[error] …"
