To follow-up my own post... some further digging with a colleague has 
led us to a possible conclusion that it's being caused by a memory leak 
in the Jetty bundled with the v4.1.2 MSI installer (Jetty v10.0.7).

Their view (at https://github.com/eclipse/jetty.project/issues/8266) is 
to upgrade Jetty to v10.0.11.

For anyone following along at home, I've raised this as 
https://shibboleth.atlassian.net/browse/IDP-1969.
