A guess -- MEM is issuing that on a timed basis, but the query is running longer than the time period. Can you slow MEM down? Meanwhile, file a bug report. You paid too much money for this kind of junior mistake. From: Sabika M [mailto:sabika.makhd...@gmail.com] Sent: Thursday, October 25, 201

If the 90 days is back from MAX(created_on) for a given customer... INDEX(customer_id, created_on) will probably be needed. And that should replace KEY `customers_id` (`customer_id`). Maybe... DELETE FROM customers_log AS a WHERE a.customer_log_id >= @left_off AND a.customer_log_id < @z
