After we set MaxMemPerCPU=9000 on a partition, we are seeing Slurm crash when we submit a job with --mem-per-cpu=.
When both -n and --mem-per-cpu= were in the sbatch script,
#SBATCH -n 1
it worked fine and Slurm automatically increased the number of CPU.
NumNodes=1 NumCPUs=3 NumTasks=1 CPUs/Task=3 ReqB:S:C:T=0:0:*:*
However, when only --mem-per-cpu= is was the sbatch script,
Slurm was crashed with the error.

[2020-03-02T10:36:42.167] fatal: cons_res: cpus computation error
In the log Slurm set task to 1, but failed due to oversubscribe.
Any idea how to fix this issue?
