Manteinance tasks not working

[TheDreadPirate]

As bitmap already stated, logs older than 3 days are deleted.

Transcode files are cleaned when the associated playback ends. If that post-playback cleanup does not occur (rare), the clean up job will only remove them if they are older than 24 hours. This is to prevent the cleanup job from accidentally cleaning up files that are still being used.

The activity log is similar in that it will remove activity entries older than 30 days. That job does not have a trigger in a default setup. I don't recall there being a setting in the UI to change that value, but it is set in system.xml if you want to change it up or down.

The clean cache job will remove files that haven't been modified in over a day.

The cleanup collections and playlists job will remove collection and playlist items that are no longer present in a library or have been moved to a different file system location.
