PETSC ERROR when simulating flow past cylinder using mpirun

[noirchen]

Hello, I am running into a PETSC error when I run the ns-code2 example. I convert the notebook to a python script and execute mpiexec -np 8 python ns-code2.py. All the test figures are correctly generated, but a petsc error of signal number 11 occurs. I installed fenicsx using conda on a linux machine with 16 cores.

The output is
