OES Netware 6.5 SP8 approximately 3 years old, used to run Arcserve does not anymore.

I have recently been fine tuning the server and noticed that NWMDKE.NLM uses a lot of memory. Forums suggest that change a setting in BTI.cfg helps but requires a reboot to take effect. I understand that this NLM is loaded by bstart.ncf and the btrieve can be stopped at the server console by using bstop.ncf

My question is that if I am no longer using Arcserve do I strictly need to re-run bstart.ncf. Are there any other processes that require btrieve?
