loki.source.file sometimes fails when rotating big files in docker

[wildum]

What's wrong?

When rotating big files (>8G), the loki.source.file component sometimes failed to register the rotation properly and kept the handle open to the deleted file instead of closing it and opening a new one to the new file.

Steps to reproduce

I couldn't reproduce the issue despite trying a scenario as close as possible to the one from the user who reported this problem and I don't have enough data to find out how this problem occurred. I'm creating this issue so that other users can share info in case they face the same problem

System information

Software version

One additional detail is that this issue has only been reproduced with dockerized Alloy that had an uptime of 6 weeks plus. It has also been seen with small files under those circumstances. So I wonder if it is not related to file size after all.
