TRACE DATABASE.TXT

LrC 10.4, Windows 10

I have a nightly backup of photos and LrC file folders. I've started to notice this file appearing but I have not had any sort of crash

C:\Users\xxx\AppData\Roaming\Adobe\Lightroom\4\Trace Database.txt

The file contents of the latest occurence are 

ClipArchiveEntry	1	5
DLIFSequenceRenderSession	1	5
DumpTracks	1	5
DynamicLink	1	5
MCBaseSequence	1	5
MCLayer	1	5
MCLayerPropertyUpdate	1	5
MCMediaCache	1	5
MCPlayer	1	5
MCSequence	1	5
MCStillFrame	1	5
MCSurface	1	5
MCSurface:GetSurfaceBounds	1	5
MCVideo	1	5
MediaCoreIF	1	5
Player.Process	1	5
Player.UpdateVideo	1	5
Wasapi initialization	1	5
dvaaudiodevice	1	5
dynamiclink	1	5
dynamiclink::FileServer	1	5
processcoordination	1	5

I can't figure out from this what the, I assume, 'trace' is of. Does anyone if this is something I should be concerned about?

Thanks
