Lights on models are "freezing" during sequence??

[Stormyblade]

Raspberry Pi 3B+ driving the show, 3 E682 controllers running models. While running sequences my mini trees and arches controller will just "freeze" while the sequence continues to play just fine on the mega tree and house lights. I've already flashed a new microSD card, no help, and swapped out the ethernet cable going from the network switch to that controller twice. Again, no help.

The crazy thing is that after several seconds (anywhere up to even a minute or two), the lights on that controller will just start up again as though they had been playing the entire time. It's almost as though the data is getting 'log jammed' and the lights just get stuck then the dam breaks, data flows again, and the lights pick up like they had never stopped.

I'm hoping it's not the E682 controller, or ethernet module on that controller as I don't have a spare...any ideas what could be causing this?

When it freezes, is there a message on the FPP status page?  It sounds like it's not returning the pings in time so FPP assumes it's down and removes it, then it starts returning pings again and gets re-added.   You can turn off the "Monitoring" but disabling the checkbox for that output on the e1.31 output page and it won't try pinging it.

If you are referring to the red text that says "Cannot ping DDP/E1.31...", then, no, I am not getting that message.

I wish I could easily embed some video of this.

Well, the lights weren't locking or freezing yesterday, but I didn't do anything except run the test pattern from the E682 for about 30 mins while checking on some things.

Ran the entire playlist for about 4 hours without a single hiccup.
