Out-of-memory handler error while running halla

Hello,

I am running halla with the following command:

halla -X otu_combined_halla.tsv -Y otu_taxa_filt_halla.tsv -o halla_output
-m spearman -v 1 --diagnostics-plot --nproc 64 --header

After running for about two weeks, I get this error.

slurmstepd: error: Detected 1 oom-kill event(s) in StepId=13608454.batch cgroup. Some of your processes may have been killed by the cgroup out-of-memory handler.

I provided about 1.5TB memory.

Please help me to resolve this error.
