This doesn't answer your question, but still: I'd be wary about using
ConstrainKmemSpace at all.  At least in the kernels on RedHat/CentOS <=
7.9, there is a bug in that eventually prevents Slurm from starting new
job steps on a node, and the node has to be rebooted to be usable
again.  See for instance https://bugs.schedmd.com/show_bug.cgi?id=5507.
(The bug report is old, but we got that result on a system with RHEL 7.7
earlier this year.)
