killing pipeline drains slurm nodes

[emosyne]

Hello everyone, I am using nextflow on a cluster through slurm.
My pipeline runs multiple slurm jobs at the same time, currently I’m limiting them to 10.
My problem is that often when I stop the pipeline with Ctrl+C, it drains one or more of the server nodes.
Reason=Kill task failed is what appears on the system slurm log.
Is there a better/gentler way to stop jobs?
Have you had similar issues? I have tried adding killBatchSize = 2 but it does not seem to make a difference.
Any help would be appreciated.
