I'm finding sometimes the message "non-active modification on ....<input_filename>".
Could anyone give us explanations about it ?
My nxlog is v2.8.1248 on Windows Server 2008 R2.
This is a debug log meaning that the im_file module detected modification on an input file that is not in the active set (i.e. closed). This should not appear in your nxlog.log with the default LogLevel INFO config setting.
