This problem occurs when you run a trace with a message that contains

AsyncOS for Email sends out an alert to the user stating that the Sophos 
Engine has expired. This occurs when you upgrade to the latest version of 
AsyncOS for Email with an expired Sophos Engine.

Workaround: You can ignore this alert. After the upgrade, auto-update 
will download and update the Sophos Engine to the latest available 
version.
