Vuo version: 

OS version: 

  • macOS 10.15

How severely does this bug affect you?: 

●●●○ — It prevents me from completing a specific task with Vuo.

Steps causing the bug to occur: 

I use a Vuo app as part of an installation and it hangs after a week or two requiring a full system restart. There doesn't seem to be any specific cause, so I'm guessing it's a memory-leak type of issue in Vuo or some related system component. But I'm not sure what I can do to help find the problem.

Have you found a workaround?: 


Other notes: 

The app is a Motion Monitor that reports motion across a video frame.

Is this a Vuo composition or an exported app? Can you please send us any hang reports or crash reports? You might see crash reports under User Reports and hang reports under System Reports. If not, when it happens again, please follow the instructions on and send us your output. Thanks for letting us know!

Hi Jean Marie, it's running

Hi Jean Marie, it's running as an exported app. I've learned a little more: the only symptom that something is wrong is the app stops working, and refuses to Quit. I didn't see anything noteworthy on the console until I Forced Quit when there were numerous mDNSResponder messages. I'm attaching those messages in case it's useful. The app has no network features (other than using OSC locally) but it does seem as though the problem has started since we enabled WiFi to support entirely unrelated network functionality. Does this info help at all?
