thank you all for your feedback.
Just to clarify this error only happens occasionally when ejecting multiple media from the command line. I've rarely encountered problems ejecting media from the GUI.
I believe this error might be related to trying to eject media when the robot is busy or perhaps when the library is inventorying itself after a loadport has been closed.
Again ... I mostly have this problem when I'm working on a remote library -- which means there very well could be people at the remote site doing stuff with the library... (opening/closing load ports.. that's all they can do..)
I'll post to this thread if I continue having a problem or if I find out from VERITAS any worthwhile info.
Thanks again for your replies!
