CEF Forum

I have noticed strange behaviour whilst running samples provided with CefGlue. Every time I execute, or debug the (winform or wpf) projects I see 3 processes running in windows task manager. Whenever the application closes all three are closed as well but this doesn't work 100%. I can't reliably reproduce the issue but time to time ghost processes are sitting in the task manager. So the questions are why there are 3 processes and how reliably to shut them down.

You should firstly read https://bitbucket.org/chromiumembedded/ ... -processes

There is exist not so many reasons to remain ghost renderer or gpu process: chromium code also not ideal and has lot of TODOs (thanks to mojo). But in most cases if you will wait long enough - they should be closed anyway.

If you not happy with chromiums process monitoring/shutdown - you always can implement own by utilizing parent/child process relationship. I'm somewhere on this forum describe this more precisely. But this kind of additional protection really needed usually very rarely / kind of workaround / soft fixing chrome code without touching chrome code.

You should understand - chrome has same defects, but usually we so rare close browser that we never hit. When you develop app - run cycles 10-100x times more, process aborts, so nightmare cases occurs which never normally occurs in release/chrome.

I am killing CEF processes, if they are still alive, just before closing the app.
