ChangesA Console Management program has been installed on one of the systems used to access the Service Processor. CauseA Console Management program, such as ConMan, has been installed on one of the systems used to access the Service Processor. The Console Management program is re-establishing the console connection after each time that the console session is stopped. This happens so quickly that any other sessions cannot take hold of the seriallink process to take ownership of the console session. SolutionEither only use the Console Management program to access a console session from the host that it is installed on, or uninstall the Console Management software entirely. If you are not sure whether you have a host with a Console Management program installed but are seeing the symptoms described then please open a call with Oracle Support who will be able to use a procedure to identify the IP address of any system that is continuously grabbing the lock on the serial link process, provided a remote support session can be provided via Shared Shell or Webex. Use the following procedure to identify which host is reestablishing the console: Whilst logged in a sunservice open another session, or have the customer do so, log in as root and attempt to start the console to check problem is still happening: -> start /SP/console
