I'm seeing this XTCOM error occur all over our /var/log/messages for one server, running SLES11sp2 / OES11/sp1;

I don't really know what this is even for. We don't use NetStorage or iPrint even, this server only does basic NCP file serving, DHCP, and hosts a GroupWise PO.
Is this anything to be concerned about?
