how to kill wrongly run mpiexec server

ParaView Support
1

Hello,
i wanted to use in paraview in parallel (please if it is not the correct way, what would it be?).
I have paraview 6.0.1 MPI-Linux-Python3.12-x86_64 version downloaded from the tar file.
first I run:
mpiexec -np 8 pvserver
which printed:
Waiting for client...
Connection URL: cs://workpc:11111
Accepting connection(s): workpc:11111
then leaved that terminal alone (not closing it nor killing it)
and opened paraview in another terminal, then hit connect→add server and leaved the default options; which look like this:

then tried to connect but I was getting the same output in the two terminals (the one of paraview and the one of mpiexec):

( 45.269s) [pvserver.0 ]vtkSocketCommunicator.c:474 ERR| vtkSocketCommunicator (0x56449b4328c0): Client/server version hash mismatch. ( 45.269s) [pvserver.0 ]vtkTCPNetworkAccessMana:313 ERR| vtkTCPNetworkAccessManager (0x56449b0a08f0): ********************************************************************** Connection failed during handshake. vtkSocketCommunicator::GetVersion() returns different values on the two connecting processes (Current value: 100). **********************************************************************
with the same current value

then I got the feedback that I should use the mpiexec that came with paraview /bin/mpiexec, but when i run (from the bin folder of paraview):

./mpiexec -np 8 pvserver
Waiting for client...
Connection URL: cs://workpc:11111
Accepting connection(s): workpc:11111
Waiting for client...
Connection URL: cs://workpc:11111
( 1.625s) [pvserver ] vtkSocket.cxx:213 ERR| vtkServerSocket (0x6546255cac00): Socket error in call to bind. Address already in use.
( 1.625s) [pvserver ]vtkTCPNetworkAccessMana:443 ERR| vtkTCPNetworkAccessManager (0x6546252308f0): Failed to set up server socket.
Exiting...

but i can not find to have a pvserver process on the htop terminal. nor killall pvserver is working (getting pvserver: no process found)

what is the solution for this? is there a simpler way to run in parallel all the time paraview?

look for pvserver and pvserver-real process and kill them all before starting again using the provided mpiexec

well, thats the thing, nor pvserver nor pvserver-real are found in htop…. nor killall…

I think you have a locally installed pvserver causing issues, please use this command:

cd path/to/paraview/bin
./mpiexec -np 8 ./pvserver

this worked, emmm i did not installed pvserver separatly.

maybe the paraview comming with openFOAM?

which pvserver will tell you.

which pvserver
/usr/bin/pvserver

strange, it is a brand new pc, that i am using since yesterday i installed the OS myself, dont know why there is this binary as i did not installed paraview otherway than simply extracting the tar file, maybe while installing openfoam.
EDIT: can confirm that comes from openfoam, i checked the version of the /usr/bin/paraview and it is 5.13 which is not the version i work with, thanks in any case.
