Does freeRADIUS tracks previous authentication results?

I'm seeing the following logs: "Login incorrect (eap_peap: The user's session was previously rejected; returning reject (again))." I'm interested in the "again" word at the end of the log. How does FreeRADIUS know that the user authentication was previously rejected? Is it because FreeRADIUS maintains a state? If so, for how long does FreeRADIUS maintain this state?
