Hi,
I was trying to setup paraview with MPI locally running
```auto
mpirun -np 4 pvserver
```
but I got this error
```auto
( 0.503s) [pvserver] vtkSocket.cxx:202 ERR| vtkServerSocket (0x5572ec0904c0): Socket error in call to bind. Address already in use.

```
Any idea on how to solve?

How did you install ParaView ?
Is ParaView built with MPI ?
Is a pvserver already running in the background ?

Hi @mwestphal
> Is ParaView built with MPI ?
I just downloaded paraview from
[https://www.paraview.org/paraview-downloads/download.php?submit=Download&version=v5.13&type=binary&os=Linux&downloadFile=ParaView-5.13.2-MPI-Linux-Python3.10-x86\_64.tar.gz](https://www.paraview.org/paraview-downloads/download.php?submit=Download&version=v5.13&type=binary&os=Linux&downloadFile=ParaView-5.13.2-MPI-Linux-Python3.10-x86_64.tar.gz)
and then executing pvserver from its /bin folder
> Is a pvserver already running in the background ?
No, there’s no pvserver already running

when running
```auto
pvserver
```
the output is:

So you are not running `pvserver` before starting `mpirun -np 4 pvserver` I suppose ?
Do you have services running on 11111 port ?

This is the output when I run

How do I check that?

Wait, what about `mpirun -np 4 ./bin/pvserver` ?

Isn’t it the same? I have aliased pvserver to ../bin/pvserver
Is it maybe because locally I have 1 GPU and paraview is trying to use 4?

Please make sure you are actually using the `pvserver` from `bin`, in this results we see:
```auto
user 1864882 1854334 0 15:29 pts/7 00:00:00 mpirun -np 4 pvserver
user 1864884 1864883 19 15:29 ? 00:00:00 pvserver
user 1865037 1862265 0 15:29 pts/10 00:00:00 grep --color=auto --exclude-dir=.bzr --exclude-dir=CVS --exclude-dir=.git --exclude-dir=.hg --exclude-dir=.svn --exclude-dir=.idea --exclude-dir=.tox --exclude-dir=.venv --exclude-dir=venv pvserver
```
Which is not `/scratch/user/Apps/ParaView-5.13.1-MPI-Linux-Python3.10-x86_64/bin/pvserver-real` as expected.

My bad… I do really apologize. It works, thanks a lot!
