Assigning to you James Newton-King (@JamesNK) as this is a new test.

StopResourceAsync hangs and doesn't stop the resource, that's why this test failed. We should add more verbose logs in DcpExecutor and ApplicationOrchestrator.

I will take a look as well

From the logs I doubt this is caused by StopResourceAsync() hanging. Rather, the test timed out because it never got a notification from DCP that the "ServiceB" process exited. Because it actually didn't. Or rather DCP never got a result of a wait() call on the process ID, despite sending (successfully) SIGTERM followed by SIGKILL to it. I am not really sure why that might be the case.

Karol Zadora-Przylecki (@karolz-ms) Another failure of this with DCP logs this time:
