[gpfsug-discuss] BIG LAG since 3.5 on quotaaccountingreconciliation

[Uwe Falke]

Hi, Jaimie, 

we got the same problem, also with a GSS although I suppose it's rather to 
do with the code above GNR, but who knows.
I have a PMR open for quite some time (and had others as well).
Seems like things improved by upgrading the FS version, but atre not gone. 


However, these issues are to be solved via PMRs.
 
Mit freundlichen Grüßen / Kind regards

Just bumping up.
When I first posted this subject at the end of March there was a UG 
meeting that drove people's attention.

I hope to get some comments now.

Thanks
Jaime
