Could not create pipe to check startup of child (Too many open files)

Hi,

I am using ONT data and I got the error in the title from the pileupCollector (in the collect.log).
I tried to increase the number of tolerated opened files with: ulimit -n 100000 and I set the batch_size: 100 in the snakemake.yml file but this did not solve the problem. Any advice on how to solve this?

Thanks a lot!
