Hi Sid,

The slurmdbd triggers purges as explained in the Wiki page:

The purge operation is done at the start of each time interval (see
bug_4295), which means on the 1st day of the month in this example.
Monthly, daily or even hourly purge operations would occur when using
different time units for the same interval:

PurgeStepAfter=2months
PurgeStepAfter=60days
PurgeStepAfter=1440hours


So you have to wait for 1 day if you have set 1000days before seeing log
lines in slurmdbd.log.
