I am running Symphony Nitris on an HP xw8200 dual 3.4ghz with 3 gig ram hooked to the Unity Storage system thru Interplay.  My issue is this...once I create a timeline and go to render it...the system may render 1%, 4%, 15%...even 50 or 60% than it stops.  I have to "keep" the rendered files and re-render sometimes 10, 12, 15 times till it renders the whole sequence.  This is happening on short vo's, long packages and 1/2-hour shows.  We have tried eliminating all of the possibilities, corrupt media, corrup graphics, starting new projects, copying and pasting known good sequences....even expert rendering than full In Out rendering...nothing helps.  And here's the kicker...it's happening in 4 edit suites all running the same software on the same platform...could this be a software bug?  We are running Symphony Nitris Version 3.0.5.

Help!
