You could set /etc/security/limits.conf on every node to contain something like

Nice suggestion, however, processes spawned by slurmd doesn't read the
/etc/security/limits.conf file.
And make sure that /etc/pam.d/slurm.* and /etc/pam.d/system-auth* contain:
session required pam_limits.so
session required pam_limits.so
Our default CentOS 7.4 file already had this:
# grep limits /etc/pam.d/system-auth
session required pam_limits.so
However, there are no /etc/pam.d/slurm.* files on our system (running
Slurm 17.02). Did TACC create a special Slurm PAM configuration file,
and is this documented in the public domain?
…so that limits are enforced for each user session. We have these lines in
several other PAM files, but those above might be the minimum set for use with
SLURM and SSH. Both sets of files might not be necessary, but if you allow ssh
to compute nodes after a job is started, you probably need both.
