Description (partial)

The number of connections on the WSA can buildup, and result in WSA becoming unresponsive

This defect occurs with HTTPs requests, when the web server connection doesn't terminate.  Typically web servers will timeout their leftover connections, but not all do, plus sometimes a firewall on web server side may blackhole these connections.
