Ted has the details, but I believe this is what we have so far.  It appears that control N2 ballast flow (which is used to control the pressure by loading the pump) is flaky, leading to process pressure control problems.  Ted has been working with the vendor to try to troubleshoot the problem to the extent of swapping out various boards.  No clear prognosis as yet, sorry.
