It’s possible that the log writer wanted to fseek to the end of the file and write something, but the target pointer value was somehow corrupted. Depending on the OS, the file might end up having a fuckton of zeroes in the skipped part.

Theoretically, yes. Theoretically NTFS supports sparse files, but I don’t know if the feature is enabled by default.

It supports it, but it’s opt-in by apps.
Enabling compression is another option (Though with a speed and size penalty), it’s user visible at least.
