I just set PriorityFlags=NO_FAIR_TREE and this seems to have solved the problem!

Every user has 0.991736 NormShares. Acataldo has EffectvUsage = 0.210193 Achowdhury has EffectvUsage = 0 But both users have the same FairShare. The correct values according to the above formula would be 0.863 and 1.0 respectively. So what's going on? On Aug 10, 2024, at 7:36 AM, Daniel M.
