Anyone have a clue what this might be or related to:

INFO: Excecuting command 'convert -limit area 2GiB -limit map 1GiB -limit memory 2GiB -alpha off -density 300x300 -adaptive-resize 1000 -depth 8 /opt/liferay/data/document_library/10154/85368/6666/1.0 /opt/liferay/tomcat-7.0.27/temp/liferay/document_preview/85884.1.0.png '

We are seeing it many times in the log and even thought it's INFO, I want to be sure it's not something I should be worried about.

Thanks!

Anyone else seeing these errors?

I believe you'll get these if you have enabled custom image resizing for the image gallery. I believe this is still just an informational message that you can ignore and/or disable.
