This message can indicate that your ChangeMan ECP license is expired. Check the Jserv.log file (Located in the ChangeMan ECP\AppServer\ logs folder in a non-custom install). If the license is expired, the log will have a message similar to the following:
A similar issue was reported by a customer using Hyena, a third party admin tool to stop the service. When the customer used Computer Manager instead, the service stopped cleanly. There seems to be an issue of the way Hyena stops services.
