I have been getting a message (lower left corner) that says "Forward8." This does not happen at every iteration of the sample, but when it does, the sampler stops and I have to hit the update button in the update window again. My model is quite complex (using some custom-built functions in WBDev), so I don't want to go into all of the details here. However, I have seen no documentation about this error message, so I cannot even begin to diagnose the problem. Has anyone else here experienced the "Forward8" error?
