While stepping through the “Developing with Wallaroo” section of the book, I set up the Celsius conversion app. When I a). terminate the sink for two minutes then restart it, or b). SIGSTOP the sink for two minutes then SIGCONT, the metrics UI freezes without updates until the sink resumes (i.e., graph doesn’t read zero during 2 min window). The same UI behavior happens if instead the source is simply halted for a while.
