Description (partial)

The UI during an upgrade times out giving the impression that the upgrade has failed.

The condition occurs when the client displaying the UI is more than moderately loaded.  During a UI-initiated upgrade, several performance and usability issues occur:

* Excess amounts of data are transmitted from the server to the UI that contain the log information
 * The excess data causes performance issues like CPU and memory utilization in the browser process on the client machine
 * Timing issues, such as long periods of no log updates, give the impression of a timeout from the UI perspective
 * Timeout errors when the upgrade has completed successfully give the impression that the upgrade has failed
