No, we didn't hit the OoM regularly until we had more traffic as we moved more sites onto the new system and it wasn't clear that there was an admitted problem with the Scala actors at first either. These days folks seem much more comfortable about admitting there's a problem with the built-in actor implementation. Is that clear enough for you?
