Thanks Ole,

this is very helpful. I was unaware of that issue. From the bug report it's not clear to me if it was just a sreport (display) issue, or if the problem was in the way the data was stored.

In fact I am running 23.11.5 which I installed in April. The numbers I see for the last few months (including April) are fine. The earlier numbers (when I was running an earlier version) are the ones affected by this problem. So if the issue was the way the data was stored, that explains it and I can live with it (even if I can't provide an accurate report for my management now) knowing that the problem won't happen again in the future.

Thanks and have a great weekend

Which version of Slurm are you using? There was an sreport bug that
should be fixed in 23.11: https://support.schedmd.com/show_bug.cgi?id=17689
