Again Quentin, which "mpiexec" program are you using? The parallel PVServer is supposed to open just one socket to accept client's connection. Otherwise it just means that the MPI context is not correctly setup. It occures if PVServer has not been built with MPI support OR you do not use the mpiexec that correspond to the MPI library used to compile PV.
