vector uninitialize

I am getting a error all of a sudden. I have a bl2600 connecting to two other devices over ethernet. I am getting a Vector 28 is uninitialized error.

Can’t find any information on it.

What “all of a sudden” caused this error?

Is it possible that you are using the wrong type of cable? Crossover vs. Regular.

Are the tcp/ip settings ok on both boards?
