Everything seems to work beautifully for an hour or two and then the web interface no longer shows live video feeds.
Full disclosure I am using CPU detection, but I wanted to kick the tires on this software before spending $ on a coral, plus the coral devices seem hard to find in stock. The relevant logs seem to be:

[2021-11-11 10:38:09] ws4py                          INFO    : Terminating websocket [Local => 127.0.0.1:5002 | Remote => 127.0.0.1:51802]

You likely need to set the shm-size

https://docs.frigate.video/installation#calculating-required-shm-size

If frigate is exiting with "Bus error" messages, it is likely because you have too many high resolution cameras and you need to specify a higher shm size.

Thanks,
Doing the math it came out to around 192MB but I rounded up to 256MB and all seems well. Service has been running all afternoon and the CPU usage is down a little too. I found RS Electronics has the dual Edge TPU M.2 module in stock so I ordered one of those.
