Comment 2 for bug 1737651

Thanks Rabi for your reply.

Actually, I am running the Sahara cluster which triggers the stack creation for heat. The heat api is all right. When I create the stack, it will create two nested stacks, one is master the other is worker. Sometimes, one of them will be working fine, and the other will hang in the "in progress" status due to no signal for WaitCondition.

I attach the template.
