We received this event after generating hundreds of millions of events on a test machine running Windows Server 2008 R2. After about 3 billion events were written, the system eventually stopped logging the actual events, and instead just kept logging event 521. There was no disk space issue, and the log was configured to overwrite events as needed. Clearing the log did not help.

The issue was resolved by rebooting the system.
