The Linux kernel default hard limit of 4096 for the number of file descriptors is quite small. Debian/Ubuntu have for a long time overridden this, increasing it to 1M. Recently systemd also bumped the default to 512k. https://github.com/systemd/systemd/blob/master/NEWS https://github.com/systemd/systemd/pull/10244 https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/thread/ZN5TK3D6L7SE46KGXICUKLKPX2LQISVX/ https://github.com/systemd/systemd/commit/09dad04c49cae3ad2b319c9b4e7773fedd34309a Here the limits are increased as follows: - slurmd: 128k; some workloads like Hadoop/Spark need a lot of fd's, and recommend that the limit is increased to at least 64k. - slurmctld: 64k; per the Slurm high throughput and big system guides which recommend a file-max of at least 32k. - slurmdbd: 64k, matching slurmctld, though slurmdbd shouldn't need that many fd's, bumping the limit shouldn't hurt either.
