Hi John, I’m sorry to hear about all the troubles. I just got a chance to look at your ticket and hub.
Those catchall messages are an indication that the source route table is being repopulated. It appears those messages have stopped, or at least stopped coming so frequently.
It also appears that all your devices are currently communicating OK just based on the Last Activity time. Due to the number of devices you have many of the internal tables used by the ZigBee stack are full or close to full, but the source route table has plenty of room so I wouldn’t expect problems with routing. If you are still having problems let me know before you reset the device and I can take another look and see if I can determine what’s going on.
