I noticed recently that my tmp directory is starting to fill up and it seems that it is filling up with file that start with dompdf_img_*. Whatever program that is creating these files is not cleaning them up or not cleaning them up as often as I would like. Does anyone know what program creates these files and if there is a way regulate how long they are kept on the server?
Using CENTOS 6.2 x86_64 and WHM 11.30.6
