That likely means that FreeRADIUS closed the connection.

Make the MySQL server respond quickly. The "rlm_sql became unblocked" message comes out because the SQL server didn't respond to one query for *many* seconds.
No amount of poking FreeRADIUS will fix this issue. It's either a slow database, or a network issue which causes connections to be blocked.
