mashtree stuck at Converting to phylip format

[SimranKushwaha]

I’m trying to run Mashtree on 12K genomes, but the process gets stuck at the step:

mashtree: mashDistance: Converting to phylip format into /tmp/MASHTREE.4DrdYc/distances.phylip
When I run the same command on <100 genomes, it completes within a few minutes and successfully generates a tree. Can anyone help me identify the issue?

Here is my SLURM script:

#!/bin/bash

#SBATCH --job-name=fn
#SBATCH --nodes=1
#SBATCH --ntasks=20
#SBATCH --cpus-per-task=1
#SBATCH --time=60:00:00
#SBATCH --mail-type=ALL

mashtree --mindepth 0 --numcpus 12 /XX/XX/XX/XX/*.fna > mashtree2_with_bootstrap.dnd
