Choose the smallest safe recovery action first, then record the prevention work that reduces repeat incidents.

같이 보면 좋은 질문
Why can rotated logs still occupy disk?

A process may keep writing to a deleted or rotated file descriptor until it reopens the log handle.

What is the practical fix?

Verify the open file handle, then reopen or restart the relevant process in the least disruptive way.
