An occasional Flash in my lights, thoughts?

[babybear]

Well I started up my show for the season what I'm a getting is an occasional Flash of white randomly within each model different places different times but not all of them. I'm running a Pi F16v2 F16v3 BBB now in the controllers test mode everything is perfect. I'm thinking it's the communication between the Pi and the controllers. It's either a bad eithernet cable or the switch. Gotten to late here for the lights and Neighbors. Anyone else had this issue?  Tomorrow I'll just start swapping out cables and jumping pass the switch. Any other thoughts

Can you isolate it down to which controller type it is on? (you have 4 types listed)

The BBB has had some updates to help with flashing problems. That is discussed on the Falconchristmas.com forum, though, not here.
