Code that works fine distributed across processes on one node using slurm seems to fail when trying to generate workers across many

Hi, I have some code that works fine when I run it on a single node of our slurm cluster using sbatch, but when I try to run it on multiple nodes I get errors similar to the following:

srun: error: cnode22: tasks 7,12,15,19: Exited with exit code 1

I am using addprocs_slurm from the ClusterManagers package and then a distributed pmap to run some computations. I can’t really see anything useful from the error above to try and debug this. I additionally get the following output from some of the workers:
