[Paraview] Problems with Paraview 3.6.1 on cluster (client - server mode)

[myaccountmail9 myaccountmail9]

Hi Ken,
thank you for your reply.
No, we didn't compile OSMesa ourselves, but we installed OSMesa library on
each node downloading the .deb packages with:

apt-get install libosmesa6
apt-get install libosmesa6-dev

Have you got any other idea?
Thank you again.
Luis
