[2.3.5.152-2.3.6.145] [C7] Help! Hub seems to be failing with repeat zigbee radio online/offline

Yes this has been confirmed by both @bobbyd and @mike.maxwell, simply do a search on it.

Example:

Thanks. A couple of things :

• the post is 5 years old - wonder if the platform handles this differently now.
• that sentence does not necessarily imply the hub is taking the radio down, just that the radio goes down when the hub is stressed. I am going to stick with my theory for now!

I did a quick search, did not find other posts as specific as that one, but did come across a post by staff stating that the hub is I/O bound, not CPU bound (makes sense).

Hub process slowdown after several days

FWIW, the CPU in the C-5 is the same CPU as the C-4, clocked a bit faster (different SOC). We did look at a faster CPU option. Here's the problem: It didn't make very much difference, and I for one would be p.o'd to pay more for something that didn't perform a lot faster. There's a reason for that: the hub is not, in general, CPU bound. It is I/O bound. You can throw a much faster CPU at it but that does not speed up the mesh networks, or the LAN. Given that most of the reported hub slo…

However I am unaware of any user-accessible stats or perf counters that allow us to monitor I/O, either on the LAN or with the radio stacks.
