Sun GlassFish Enterprise Server 2.1 Release Notes


Sometimes, a resource contention problem on the server may cause a management client to become disconnected, When reconnecting, a misleading error message "hadbm:Error 22184: A password is required to connect to the management agent" may be returned.

Check if there is a resource problem on the server, take proper action (e.g., add more resources), and retry the operation.
