It occurs on web servers reachable through the net. After approximately 1 week the machine runs with 100% cpu. Looked like the classic infinite loop, used jstack and our own web tool with similar functionality to identify the thread/code that's causing the issue, but there was no active thread. No (visible) code from us and no jetty code.

I think I did not see the issue on any of them, but I suppose it's more likely to be because of the box being not public rather than because of Windows.

Please open an issue (https://github.com/jetty/jetty.project/issues)
and let's discuss there.
You can get suggestions about what to try, and you can provide attach
to the issue e.g. log files, configurations, stack traces, etc.
