I have the latest version (6.2.0u) and it works great at the default settings. I noticed that if I set the restart delay to anything other than 0 then the plugin never restarts anything. It doesn't matter to me, I just leave it as 0, I am just mentioning it.

That's interesting, thanks for the note. Maybe grab a debug log or several with the various settings and when a channel is restarting? Beware that the debug log contains URLs and authentication credentials, so probably best if not published (but if you do get it, I'd like to see it privately to try and understand what's going on).
