Hi Gérard,

The way you are checking is against the association and as such it ought to be 
decreasing in order to be used by fair share appropriately.
The counter used that does not decrease is on the QoS, not the association. You 
can check that with:

scontrol -o show assoc_mgr | grep "^QOS='+account+’”

That ought to give you two numbers. The first is the limit, or N for not limit, 
and the second in parenthesis the usage.

Hope that helps.

Best,

Miguel Afonso Oliveira
