ConnectionManager.getConnection() failed to obtain a connection for MySQL

When attemting to connect to a MySQL database, I receive the following error message.

org.jivesoftware.database.DefaultConnectionProvider.getConnection(DefaultConnect ionProvider.java:68)

Warning: DbConnectionDefaultPool.getConnection() was called before the internal pool has been initialized.

org.jivesoftware.database.DbConnectionManager.getConnection(DbConnectionManager. java:107)

WARNING: ConnectionManager.getConnection() failed to obtain a connection.

Per above how do I initialize the internal pool?
