error outputs when running and closing mpi examples in a docker container

[ghost]

I am trying to run mpi examples inside a docker container using X-Server to show the GUI. When I run provided examples, I get the following errors. Despite the errors, the programs runs fine.

ospray@d49abb85a656:~/build-container/install/ospray/bin$ mpirun -n 2 ospMPIDistribTutorialSpheres

OSPRay rank 1/2

ospMPIDistribTutorialSpheres runs fine despite the errors.

ospMPIMultiDisplays also runs fine despite the errors. These errors appear when you close the program.

open-mpi/ompi#4948 discusses about Read -1, expected <someNumber>, errno =1. In short, the issue may have been addressed in a new version of MPI.

I have not tested it yet. I need to look into this problem more close. The docker container has mpirun (Open MPI) 2.1.1.
