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

[Florian Zillner]

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

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.
