To be more specific, follow from function to function: cleanup.c -> mysql.c -> db_deletequery(); db_deletequery() .. count=0; .. start: .. /* fire off query */ if (w_mysql_query(fd, "db_deletequery") != 0) .. /* MySQL does not handle extremely large deletes very well */ if((int)mysql_affected_rows(mysql) == 100000) { count=count+(int)mysql_affected_rows(mysql); goto start; ^^^^^^^^^^^ | Re-run the delete query if we hit up against the 100 000 limit as this gives MySQL a small "breather" window. (Keep re-running the delete query until there is less than 100 000 rows deleted) Running cleanup in DEBUG=3 mode shows you what is happening in step-by-step detail.
