Hello,

I have encountered issues with running slurmctld.

From logs, I see these errors:

[2024-06-14T17:37:57.587] slurmctld version 24.05.0 started on cluster laura [2024-06-14T17:37:57.587] error: plugin_load_from_file: dlopen(/usr/lib64/slurm/jobacct_gather_cgroup.so): /usr/lib64/slurm/jobacct_gather_cgroup.so: undefined symbol: xcpuinfo_init [2024-06-14T17:37:57.587] error: Couldn't load specified plugin name for jobacct_gather/cgroup: Dlopen of plugin file failed [2024-06-14T17:37:57.587] error: cannot create jobacct_gather context for jobacct_gather/cgroup [2024-06-14T17:37:57.587] fatal: failed to initialize jobacct_gather plugin [2024-06-14T17:39:07.741] Not running as root. Can't drop supplementary groups

Aftre setting

#JobAcctGatherType=

the problem changed to:

I also tried that with git-master:

Any idea what may be wrong?

Recent compiler-hardening efforts broke slurms way of loading plugins. As a workaround, link slurm with -Wl,-z,lazy
