Facet growth would come from the meshing tools. Splits in poly face meshes occur where you have a surface boundary split, possibly from a surface label change or sharp angle. 

Re the film heat transfer, the problem tends to arrise from the amount of energy being added to the (almost nonexistant) film or near wall cell. If the near wall region is over refined then the source terms can become high.
