Second instance's camera and web portal randomly crashing

[ahmad-najeeb]

Hi Paul. First thankyou for this script. Really awesome!

So I used your script to setup two instances yesterday. Both are Creality Ender 3 printers but different models. I also added one camera to each of them. Both cameras however are the exact same model with the same serial number (which is actually just the model name). When I added the second camera to the second instance, I was warned that because that serial number is the same as a previously added webcam, there can be instability.

The above being said, I setup both instances are they're working fine, cameras too. The issue however are two things:

• After about 30 - 90 seconds of streaming, the second instance's camera starts blanking out or stuttering randomly. If I refresh the stream webpage, it starts playing again. If I play the stream in VLC, I notice the same thing that it's sometimes stuttering/pausing.
• The second instance's webpage portal also crashes after a few minutes. By crash, I mean the page would stop syncing and I see the 'Aw, snap' error in Chrome (error code: STATUS_BREAKPOINT). Tried another browser and same thing. But if I refresh the page, it reloads fine.

Both above issues don't mess with anything that's printing, which continues fine. I just have to keep refreshing which is annoying. Also both issues only happen with the second instance. Neither has happened to the first instance even once.

Any ideas what could be the issue ?

It is hard to know for sure, but my first guess for the stuttering camera is simply that you are running out of wifi network bandwidth. Decrease the resolution and FPS for the cameras and see if that improves things.

For the webpage stopping, I would open browser console and see what message you get when that happens. I suspect possibly a plugin, though it may also be that the socket is timing out because the device cannot keep up with network traffic due to the cameras.
