I do not remember ever coming across this issue. I was prepping for a startup and was checking to make sure everything was good, and I happened to notice that the Ref Counts column in “Configure IO Units” dialog box was showing a large number of references. Did they recently add or change this column? I could swear that in the past that this column if existed indicated only the reference counts from the strategy itself. Of course when I saw these number and could not explain them, I was freaking out…
After much todo about nothing, I discovered that at present, this column is the total references of both the actual IO points configured on the specific brain and the total references to the brain from the strategy. I found absolutely no reference to this in the help files.
