Hi,
The Resource Manager can automatically switch a session to another consumer group when a certain condition is met.
Automatic switching can occur when:
A session attribute changes, causing a new mapping rule to take effect.
A session exceeds the CPU or I/O resource consumption limits set by its consumer group.
So i suppose in this case second condition might have fulfilled so you are seeing the change.
