I suggest contacting SmartHome/SmartLabs about this problem. My sense is that they are quite motivated to make Insteon a success, and I suspect that they would want to find out why this is happening, and figure out how to keep it from happening in future installations.

Hooking up a DSO with a nice long memory would tell them exactly what's going on during an event.
