I have a set of programs (derived from Eric P. Scott's IWF 2.0) which receive  
PostScript files from a main server on the net, rip them using the  
machportdevice operator, create Xerox 9790 interleaved graphic files and send  
the graphic files back to the main server to be printed.  I use the  
machportdevice operator and the NeXTLaser-300 pixel encoding dictionary.  Under  
NeXTStep 2.1 this setup worked fine...  Now I have upgraded to 3.0.  When I get  
certain files which have the image operator in them, I get this error on the  
console:

Oct 14 10:52:11 clients-r-us WM[process#]: DPS client library error: Error  
while writing to connection, DPSContext context#, data -102

for each process that is using the windowserver.  The cursor disappears and  
then BANG!...I'm logged out.

If I use the NeXTCBJ pixel encoding dictionary everything seems to work o.k.
In <mach/message.h> -102 is defined like this:

#define SEND_INVALID_PORT	-102	/* Reference to inacessible port */

Have I stumbled on a bug in NeXTStep 3.0?  Am I even looking in the right  
direction?  Is there a way I can rip PostScript files with PostScript Level 2  
without even using the machportdevice operator?  Are there any examples out  
there?  Am I asking too damned many questions?
Please reply to bizarre@clients-r-us.tamu.edu
