Blast example stuck

[ai4pharma]

I'm trying to run blast.nf in my workstation, blast_result and top_hits have been generated, then the project stuck. Any possible reason?

nextflow run examples/blast.nf -with-docker -with-report -with-timeline

I've seen this problem when there's not enough memory to run the container. Could it be the case?
