To give more information on this issue. We are heavily using cups lpd daemon (via inetd) because the machine is used to convert from some old systems, old fashioned printer that do not exists no more, and cups is able to convert this in whatever we want (pcl, pdf, postscript) via its powerfull drivers plugins system.
So cups.lpd might be involved in this issue, because we dont have this issue on system that do not run cups.lpd
