PHP Error Log says "Error in SQL Syntax"

I get this in my php error log:

WordPress database error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘status timestamp <= 1300000537 and id not in (select redirect_id from wp_wbz4’ at line 1 for query select id from wp_wbz404_redirects where status = 2 status timestamp <= 1300000537 and id not in (select redirect_id from wp_wbz404_logs) made by do_action_ref_array, call_user_func_array, wp_cleaningCron
