Could it be a problem with mismatched libraries? I notice in the error below that it occurs in /usr/lib/libGL.so.1. This is a system library. Did you compile OSMesa yourself? If so, then you should not be using the system GL libraries; you should be using the libraries that you compiled when you also generated the OSMesa library.

we have a Linux (Debian) cluster without gpu and we have a big problem using Paraview 3.6.1in client - server mode.
The server has been compiled with OSMesa library and following the instructions reported here (in particular the section "OSMesa support"):
If we try to connect the client started with the command:
and the server, started with the command:
we must disable the checkbox "Remote rendering threshold" (but this causes bad performances) in the client settings (Edit -> Settings -> Render view -> Server), othervise Paraview crashes after loading a big input or performing some operation such us changing "outline" to "wireframe"...
The error always is (similar to):

This error also occurs if we start client and server logging directly (without any ssh connection) on the master node; on master node X is running and we can execute the test:
mpirun -np 4 /usr/X11R6/bin/glxgears
So, it doen't seem a problem regarding X connection and permission...
Moreover, executing the test:
/ParaView/ParaView-bin$ ctest -I ,,10
we obtain some segmentation fault, but the log file can't give any useful information.

On our local machine with gpu 100% test passed, and we haven't any problem to connect client and server on that machine.
MPI version is: mpirun (Open MPI) 1.2.7rc2
OSMesa version is: 7.0.3-7
We searched on google, on Paraview wiki... without any succes: can you help us please?
If you need more information let us now
Thank you very much
