To start we are only at ~700k events of our 2.5MM for the month. I have a bunch of devices which after running for a time will be on line (breathing cyan), show in Particle Cloud as online, but no events are being received from the device. During this condition I can call functions and request variables from the device.
Restarting the device corrects this issue. After restarting, the device goes online and events start flowing again.
I am not really sure where to start troubleshooting here as the events just stop. There are three events published. One every 10 seconds, and two others every 30 seconds.
Any help in a direction on troubleshooting is really appreciated .
