Can someone interpret this for me? (Shark tools)

[John01021988]

My system is beachballing every 3 minutes or so, I read in a thread that by installing Shark tools and doing a system trace when the error occurs, you might find the source of the problem. I did a system trace and I keep getting postmaster processes when the beach balling occurs (100's of em in 5 seconds)
How do you interpret the problem?

Did you install PostgreSQL?

The postmaster also manages the communication among server processes.
