change: [1,2] means that objects with handle 1 and 2 are invalid. 1 is usually the app.
If there is no Id in the package it means that it is not a reply but a notification. Is there another process working with the app? Perhaps a reload? That might explain 'suspend' that I have never seen before and seems undocumented.
Hope this helps
