It's very strange, I have never seen this.
Now that I look at the server dump, it's strange already.
Yours:
org.eclipse.jetty.server.Server@f415a95 - STARTED
+= ServerConnector@9f46d94{HTTP/1.1,[http/1.1]}{0.0.0.0:10001} - STARTED

Normal:

What's missing in yours is the dump of the JDK Selector itself as a
child of the ManagedSelector, and the SelectionKeys, despite you have
200+ for each ManagedSelector.
Looks like the JDK selector has been closed, or some Jetty component
has been stopped ?
Can you open an issue and attach there a reproducible case, or give
instructions on how to reproduce ?
