CEF 3.2623.1395.g3034273 x64:
There is .NET process.
Process hangs or may be no, unfortunately it is impossible to reverse from dump in current state.
But debug diagnosis shows some weird exceptions like OutOfMemoryException, StackOverflowException, ThreadAbortException, ExecutionEngineException without additional info. They just happens. So i'm think that process crashed and tried to shutdown (and this is why ThreadAbortException appear, i'm never abort threads).
But, unfortunately process actually did not finishes for a long time. It is just exists, renderers exists, no-one consume CPU / etc. Browser process have exactly one thread (looks like main thread), and callstack of this thread is. Can someone give me pointers or insights to what it can be / how it is better to handle?
I'm potentially can call CefQuitMessageLoop with living browsers, but feel that i'm do not do that.
