Useless information being written to "deep analysis" log files many times per second. Normal?

I was trying to find something in my logs and I looked at the “Plex Media Scanner Deep Analysis” log files on the server… and they are filled with pretty much nothing bug the same thing … hundreds of thousands of lines of this. 15MB of it in the last few days. Is that normal? It seems very excessive and not at all useful

One of my log files is 61,000 lines long and all of those lines account for only 21 seconds of output, spanning from 02:03:39.064 to 02:04:00.466

Multiple times per millisecond

If it becomes an issue like hundreds of thousands of repeats and is widespread, we can discuss with the developers to see if they can be silenced - so will monitor the situation. Please keep the media files giving rise to this just in case they would be needed

@sa2000 I looked over the log files and all of them mention the same movie file. Although it could happen with others using the same codecs, not sure… it seems plex only keeps a limited number of these deep scan log files at any given time. Here’s a ffprobe dump of the file https://pastebin.com/raw/Tzutm1gc

I will keep the file
