When the X will not stay it seems to be because the FEE64 cannot open a > connection to the Server. -------- Entry 230 was to help when the rates in the fastest part of the system caused one of the FEE64 to be blocked for > control access while waiting for the slowest to produce data. Judging by the next entry in this diary I think this is now understood but .... 'belt and > braces' seems a good idea ;-) > > I've not seen the 'H' disappear but it could similarly mean that the enabling of Histogramming is failing.
