@Jeff_Gallagher How many devices? How many running drivers (not just installed, but with devices assigned)?
My own experience is that the v3 starts going downhill at around 15 running drivers on fw 45. I’m sure there are other factors involved (I have around 125 devices, almost all hub-connected, some interacting with the hub quite frequently), so your number may be different.
@Automated_House Are all 27 drivers actually running, or are some installed but not in use? That’s a lot to run based on my experience (though with fewer hub-connected devices, maybe it’s ok). Try running logcat for a little while on all drivers to see if you’re getting frequent driver restarts, which would be a sign that you’re running too much. My understanding is that the message is based on memory, not storage, so I suppose you could see it come and go depending on what’s actually happening on your hub.
