OS: windows 10
I run the elasticsearch.bat to start a elasticsearch instance
when I post a wrong request, sometimes the elasticsearch paused, then not response any more,
until I press any key in the command window, it works again, but it not always can reproduce.
I've seen similar things in the past but it was a Windows issue whatever application you are running.
When you press scroll lock or click in the window to select some text, it blocks the running process.
