 This could be caused by a mismatched connection limit between the Fleet server and the MySQL server that prevents Fleet from fully utilizing the database. First [determine how many open connections your MySQL server supports](https://dev.mysql.com/doc/refman/8.0/en/too-many-connections.html). Now set the [`--mysql_max_open_conns`](./configuring-the-fleet-binary.md#mysql_max_open_conns) and [`--mysql_max_idle_conns`](./configuring-the-fleet-binary.md#mysql_max_idle_conns) flags appropriately.
