In the hopes of getting faster render times we have been testing an IBM Intellistaion with dual Xeon processors and 2 gigs of RAM. It also has the Nvidia Quadro4 980XGL card.
We're testing a rendered walk-around of one of our models. We ran a 50 frame segment successfully and got great results compared to our standard P4 station. However, when we tried to run a 150 frame segment, we found that 16 hours later, when it should have been done, it was only half way through and a "running low on memory while rendering" Revit error had appeared. I also noted that the elapsed time in the Revit status bar said only about 6 hours.
We have tried rebooting prior to starting the rendering session to make sure everything is cleared. No other programs are running during this time. We are connected to a network and it is possible that background programs may make demands on the station.
One of our IT staff looked at the record of the system's memory usage and it looks OK. He wonders if Revit is not properly "releasing memory". We have noticed that when the error occurs and you drag the warning dialog around the screen it leaves a video trail, suggesting that the problem is with graphics memory.
I should note that we also have gotten this error on our P4 stations - that's one of the reasons we wanted to try a more powerful box. But if this is a Revit or Accurender bug that happens even on an Intellistation Z-Pro, I can't see spending a large amount of money just to continue getting errors. If we need a rendering or walk-around for a meeting, I don't want to come in the next morning only to see its not done due to this error.
Any help would be appreciated.
