Question
Why is parallel count higher than the queryprocs setting?
Answer
The parallel count value from set stats full output can be higher than the queryprocs setting. This is working properly. The queryprocs setting is an upper limit on the parallelism per query at any point in time. During query execution when a process finishes another process can start. The parallel count value is cumulative and adds the total number of processes during query execution.
