This could be for a wide range of reasons. You should start a new thread and give us some more details. For example, are the entities with contention warnings global to all users or user specific? Is the contention caused by user requests or tasks? What are you doing, updating a counter? Be sure to give us enough information to help you.

Clearly it's not due to traffic because it's like 5 of us testing the site at this point. I'm a bit worried our patients/doctors will see this after launch next month.
