    It is quite possible that the system really is running
    out of its ability to lock pages.  Too many are already
    locked?
    
    Without knowing what the application is doing, how much
    memory there is, how much DMA activity, what the various
    system parameters are, it is impossible to speculate.  You
    can stop the graphics card from doing DMA via an environment
    variable, if you think that might help.  Has the system 
    always done this?  If this is a new phenomenon, you might
    ask, "What has changed recently?"
