I can imagine during the late night the job status may go idle but at least during the day time the interactive session shouldn't be idle especially with high resource `>20GB`.

To limit the ability of clogging the cluster with interactive jobs there are already two measures in place: a limit of max 5 jobs per user and a max walltime of 72:00:00 hours. Just as a contrast, if I ask for a batch job with very poor memory utilization but block a whole node for this (e.g., by mem=250gb), there are currently no limits in place to prevent this and I think this is the more general source of memory waste."}}
