Summary

After initiating a promote_content, the promotion process takes significantly longer than normal.

Eventually, a SEVERE message is logged in the App.0.0.log, and any remaining remote Assemblers are updated.

The issue occurs intermittently, and does not occur if the remote application servers are frequently restarted.
