Distiller Server "Could not open file" modal dialog

Question

We're running Distiller Server 8, and I've got a dilemma that I'm hoping is solvable.
This is installed on a Windows 2008 server, with jobs coming into watched folders from our OPI server. Periodically, we get a dialog box that says Acrobat Distiller "Could not open the file: P:\OPI_Data\PDF_Processing\Index_PDFs\out\<filename>". The path specifics will vary, but it's always a path to a file in process... not to a config file or anything like that.
The big problem is that this pops up as a modal dialog and Distiller won't process any more files until someone clicks "OK". On the console. On a server. In the datacenter. We run two shifts, and I'm getting really tired of phone calls at midnight saying "Distiller is hung... can you fix it?"
Is there a way to run Distiller Server in silent mode? Some way to tell it "If you have a problem, just fail that job and move on"? Having to have a server administrator connect in and click a dialog box is just silly.

That seems to have done the trick, thanks.  I don't really like doing forces unless someone who knows more than I recommends it, as I see way too many threads where that has complicated things tremendously.
