> I was baffled looking at L1 Cache because it was stuck at 100k blocks and only 'loading' 3G of data according to the UI. When I looked in log, all the numbers looked write in the Cache summary reported in log.
> Turns out our buckecache UI template will cut off calculating stats at a limit --which is probably what we want -- but the fact that it has done this should be more plain.
