[need more information]
Could you please be more specific. In which directory you are ? (scratch or home ?) (full path directory)

Feel free to add any information you think is relevant.

possible root cause

  • You are trying to do an ls in a large directory (containing many files).
  • Performance issue on beegfs due to the maintenance (all user are on Yggdrasil).
  • Performance issue on beegfs due to a job doing too many IO scratch or home directory.
