Ghost 14-VPROSVC memory usage

We have an XP PRO  laptop with 2GB RAM running Ghost 14. We have been having some strange things happen. Looking at task manager, I see the memory usage for VPROSVC constantly increasing. We have no scheduled backups. We run two different ones on-demand to a USB external hard drive. I think our problems are related to VPROSVC using up memory. Why would it be constantly increasing?
