I've recently updated an OS 1.8.0 model to 1.9.0. The model ran fine in 1.8.0.

When I run the model in 1.9.0, it says it fails. The OpenStudio results are not shown. However, the EnergyPlus results are shown and the eplusout.sql data seems to be intact... It appears as though something failed after the EnergyPlus run completed - but I can't find what went wrong. Any ideas?
