Palo Alto Networks - Defect ID: PAN-152743

Fixed an issue where, when initial flows from both directions reached the firewall at the same time, a race condition occurred, which caused the firewall to display the following error message: Duplicate flows detected while inserting <number>, flow <number> with the same key . The flow keys were identical due to the flows having the same SRC and DST ports.
