Issue Details

I have a cRIO which crashes when I have a "Run at Startup" VI. This VI calls my main VI which uses channel wires. After it crashes the Status light on the cRIO blinks 4 times. What should I do?


This is related to a known error that is being worked at the moment. As a work around, you can go to you Build Specs of your Main VI. Go to the properties. Then under "Additional Exclusions" uncheck the "Disconnect type definitions." When that's unchecked, it should work. Otherwise, you can replace the channel wire with a queue.
