[slurm-users] Sinfo or squeue stuck for some seconds

[navin srivastava]

Dear slurm community users,

We are  using slurm version 20.02.x.

We see the below message appearing a lot of times in slurmctld log and found that whenever this message is appearing the sinfo/squeue out gets slow. 

No timeout as i kept the value 100.

Warning: Note very large processing time from load_part_uid_allow_list: usec=10800885 began=16:27:55.952
[2021-08-29T16:28:06.753] Warning: Note very large processing time from _slurmctld_background: usec=10801120 began=16:27:55.952

Is this a bug or some config issue. if anybody faced the similar issue.could anybody throw some light on this.

please find the attached slurm.conf.

Regards

Navin.

Hi Navin,

could it be that you're using LDAP/AD/NIS for user management? If so, check if the LDAP servers response is slow or gets slowed down when retrieving hundreds or thousands of users.

Also CacheGroups=1 was last supported in V15.08.

Best,

Florian
