[logback-user] deleting the log file stops logging

[David Roussel]

Is this on Unix? On windows you wouldn't be able to delete the file. 

On unix if you delete a file and another process is writing to it, then the file still exists until it is closed. So logback does not know the file has been deleted. 

Just try to not delete it.
