This article applies to:

• Trustwave MailMarshal (SEG)
• Trustwave ECM/MailMarshal Exchange

Symptoms:

• Restarting MailMarshal services
• Starting MailMarshal services in debug mode
• Error message: Initialization error. Unable to initialize RPC server
  Make sure you are not already running MailMarshal Engine
  1740 - The endpoint is a duplicate
• This error can be raised by any MailMarshal service. The service is named in the error text

Causes:

• The service you are starting or re-starting is already running.
• MailMarshal services under load can take considerable time to stop, because they must complete existing transactions first.

Resolution:

• Ensure that the relevant service is stopped and then try again.
• The preferred action is to wait for the service to stop. You can end the service forcibly, but Trustwave does not recommend doing so as data might be lost.
