Every so often all of the components on all of the running instances of my application go into an error state for about 5-10 seconds and then goes back to normal. I don't see anything in the logs that would explain it. Does anyone have any suggestions?
By all of the components, do you mean every single container, label, text field, and so on OR every component that is bound to a tag in some way? Can you show a screenshot of what it looks like when it's in the error state?

Sorry, every component that is bound. The screen shot is a little tougher. We are in high security environment.
Sounds like a comms dropout between gateway and PLC. You should run wireshark in ring buffer mode so you can capture what's happening on the network when your clients go bad.
(Is it possible that you have engineers modifying the PLC code? That often disrupts live polling.)
It's multiple PLC's running different instances and it all happens at the same time. I will try wireshark.
