Description

I've been testing checktable operations extensively in SQL Server 2016 SP1 cu0, and changing DOP from 1 to 8 on an 8 vcpu VMware vm.
OLEDB waits always seem to update in os level wait stats; not always in session level wait stats.
Some scenarios cause session level OLEDB waits not to update in checktable operations with MAXDOP > 1, some conditions cause session level OLEDB not to update with MAXDOP = 1.
