Quicklook Errors in System Log on 10.12.6 Server 5.2

Hi,

I upgraded our SMB Server from 10.11 to 10.12 and started getting these in my system log.

This is just a snippet; they go on for weeks. What I'm not sure is: are these a problem with clients using quicklook on files form the server? Or quicklook on the server itself? Any idea how to get rid of them; they're filling up my logs.

Thanks,

Jeff
