When I use the client-server mode in the linux cluster, where I start multiple pvserver processes using OpenMPI and connect from a paraview client, the following error appears.

```auto

```

However, for the same model it works OK in a standalone.  
Please note that it is the same version of paraview used in client-server and standalone.

How to overcome the issue in client-server run of paraview?
