recently I upgraded to v 6.0.1 and I noticed that calling pvserver by mpiexec prompts n times connection waiting messages.
$ mpiexec -n 3 pvserver

I’m testing this on my local machine (windows 11). Also after making the connection using paraview GUI, under memory inspector tab, only one processor is connected.
I downloaded ParaView-6.0.1-MPI-Windows-Python3.12-msvc2017-AMD64.msi from www.paraview.org/download/ and followed the installation procedure using the default settings.
