I attempted to stop radius - /usr/local/etc/rc.d/radiusd stop  and restart MySQL - /usr/local/etc/rc.d/mysql-server restart But that did not work. when I ran a tail command on the radius.log file, I got these errors: Tue Jan 7 20:18:00 2014 : Error: Failed to load clients from SQL. Tue Jan 7 20:18:00 2014 : Info: rlm_sql (sql): Closing sqlsocket 4 Tue Jan 7 20:18:00 2014 : Info: rlm_sql (sql): Closing sqlsocket 3 Tue Jan 7 20:18:00 2014 : Info: rlm_sql (sql): Closing sqlsocket 2 Tue Jan 7 20:18:00 2014 : Info: rlm_sql (sql): Closing sqlsocket 1 Tue Jan 7 20:18:00 2014 : Info: rlm_sql (sql): Closing sqlsocket 0 Tue Jan 7 20:18:00 2014 : Error: /usr/local/etc/raddb/sql.conf[22]: Instantiation failed for module "sql" Tue Jan 7 20:18:00 2014 : Error: /usr/local/etc/raddb/sites-enabled/default[177]: Failed to load module "sql".
