[Paraview] Crash with Parallel Pvserver, Off-screen rendering

[Gregory, David C CIV NSWCDL G24]

Unfortunately, I can't post the errors or the CMakeCache.txt.  I'm
hoping to have another machine to run on in a week or so.
 
However, in this particular case, there are no "X" errors.  There is a
vtk-paraview error regarding a failed server connection, and then the
application abruptly quits.
 
However, I'm a little confused.  If I'm using a Mesa enabled server,
with off screen enabled at compile time and on the command line, should
I need an X server?

	It sounds like a configuration problem. Can you post the X
errors? I am guessing the server does not have access to an X display or
one that supports GLX. Also, can you post your CMakeCache.txt?

		Hi-
		
		I'm running a CVS snapshot from 20 Sept of Paraview 2.5,
compiled with
		mpich-gm, Mesa-6.5.1 and off-screen rendering enabled in
cmake.  I also
		have a version compiled with mesa and off-screen but
without mpi. 
		
		I start paraview as follows:
		
		/paraview-cvs-mesa-nompi/bin/pvclient -rc
		
		/paraview-cvs-mesa-mpi/bin/pvserver -rc -ch=headnode
		--use-offscreen-rendering
		
		If I un-check the "compositing" box in the GUI, which as
I understand 
		things, disables compositing and does all rendering on
the head node,
		paraview runs fine.
		
		However, if I turn compositing on, the SERVERS crash
immediately if any
		data is loaded for display, and I get a message from the
client which 
		informs me that connection to the server has been lost.
There are no
		X-related errors in stdout or stderr - only a message
which gives an
		error in the vtk server connector.
		
		Is this likely a bug or a configuration problem?
