Problem with ulimit -Hn. ERROR: The system limits on the number of files a process can open is too low.

Open Felipe-ia opened this issue 2 years ago • 1 comments

I'm having trouble changing the ulimit -Hn. I already changed it to 188456 files but when I run it again, it asks to change it to 188456 again and it was already changed. CODE (orthofinder) fcasais@tyrion:/media/dragonstone/fcasais$ /home/fcasais/miniconda3/envs/orthofinder/bin/orthofinder -f /media/dragonstone/fcasais/4-Anotação_Prokka-2/Prokka_faa/

ERROR: The system limits on the number of files a process can open is too low. For 434 species OrthoFinder needs to be able to open at least r=188456 files. Please increase the limit and restart OrthoFinder

  1. Check the hard and soft limits on the number of open files for your system: $ ulimit -Hn $ ulimit -Sn
  2. If hard limit, h > r already, then you just need to increase the soft limit: $ ulimit -n 188456
  3. Alternatively, if h < r then you need to edit the file '/etc/security/limits.conf', this requires root privileges. To increase the limit to 188456 for user called 'emms' add the lines: emms hard nofile 188456 emms soft nofile 188456 (edit these lines to match your username)
  4. Check the limit has now been updated (if you changed the hard limit you'll need to open a new session and confirm it's updated): $ ulimit -Sn
  5. Once the limit is updated restart OrthoFinder 'from trees' using the '-ft' command
