Hi, I have a C8 Pro and have received this message a few times in the last day or so. "ZigBee radio has gone offline or check processor isn't close to overload appears". I think it's attributed to this error linked to Maker API. Does anyone know what would cause such an error and how to resolve please? Appreciated 
What is app 842? Are you using HD+? See these posts. Corrected with battery restrictions.

Hi, so App 842 is Maker API. Yes I'm using HD+ which could tie in here. I can't quite understand how others have resolved the issue though based on the 2 posts above. Any ideas?
From his post:
"I was able to correct the multiple errors in the log by adjusting the "unrestricted battery" setting for the HD+ app on my Samsung phone. Thanks to those who pointed me in the right direction and helped me find this solution."
Set the HD+ app battery permissions to Unrestricted
Do you POST a lot of device events ?
EDIT: the reason I ask is that the error you are seeing is because MakerAPI is making (too many) calls out to something. The technical explanation is that apps have a pool of up to 8 concurrent HTTP calls that can be pending at any given time. You have way more than that.
Things to try:
- identify the device(s) spamming events & remove them
- reduce the number of devices you post events for
- split devices across multiple instances of MakerAPI
The zigbee radio reboot symptom can still happen when the hub is overloaded. What does http://(your hub ip)/hub/advanced/freeOSMemoryLast say for CPU avg when the errors occur ?
