[slurm-users] slurm continously log _remove_accrue_time_internal and something underflow error

[taleintervenor at sjtu.edu.cn]

Hi all:

 

We found out slurmctld keep log error message as

[2022-06-16T04:01:20.219] error: _remove_accrue_time_internal: QOS normal
accrue_cnt underflow

[2022-06-16T04:01:20.219] error: _remove_accrue_time_internal: QOS normal
acct acct-ioomj accrue_cnt underflow

[2022-06-16T04:01:20.219] error: _remove_accrue_time_internal: QOS normal
user 3901 accrue_cnt underflow

[2022-06-16T04:01:20.219] error: _remove_accrue_time_internal: assoc_id
2676(acct-ioomj/ioomj-stu3/(null)) accrue_cnt underflow

[2022-06-16T04:01:20.219] error: _remove_accrue_time_internal: assoc_id
2623(acct-ioomj/(null)/(null)) accrue_cnt underflow

[2022-06-16T04:01:20.219] error: _remove_accrue_time_internal: assoc_id
1(root/(null)/(null)) accrue_cnt underflow

But slurm itself seem to work well and using sacctmgr query the reported
user/account all seem to be ok. 

So what is the underflow mean? Is it imply some kind of mismatch between
slurmdb datebase records?

How can we fix the problem and stop slurm to report such message?
