[slurm-users] Power Save: When is RESUME an invalid node state?

[Stefan Staeglich]

Hi Xaver,

we also had a similar problem with Slurm 21.08 (see thread "error: power_save 
module disabled, NULL SuspendProgram").

Fortunately, we have not yet observed this since the upgrade to 23.02. But the 
time period  (about a month) is still too short to know if the problem is 
really fixed as we are still in the normal recurrence period of that event.

Best regards,
Stefan
