2.3.1.X child device continually disconnecting / connecting from Hubmesh

Running 2.3.1.130 now, but I also saw this behavior on 2.3.1.128:

I have an Inovelli LZW36 light/fan combo switch, included with NO security and shared via Hubmesh. Hubmesh doesn't allow sharing the child devices - only the parent device is shared. On the subscribing hub, I see many many events describing the child devices disconnecting and then reconnecting to Hubmesh, this happens every 5 seconds, and happens for both child devices. I switched my Hubmesh to TCP, but it didn't change the behavior. Here's one page of events:

Are all devices (parent and child) enabled, or are some of them disabled?

I had this same problem with a Zen30 a few months ago. I removed and reincluded the device and havenโ€™t had a recurrence.

All devices are enabled on the main hub and respond to local and zwave commands.

Found the problem. Somehow when I excluded and re-included the switch to eliminate S2 security, the sharing via Hubmesh got borked. On the subscriber side I had two copies of each child device... for each real device, I had a fake one that was spamming the logs. Deleted the problem children from the hub... hopefully this takes care of things.
