> The ITBLL cluster configures block cache capacity to 512MB, but the memtracker is reporting 685MB of usage. It's clearly not un-bounded, because this server has been up for days doing lots of work, but we're either not properly counting the memory, or not properly respecting the configured limit. Maybe we're only counting the values and not the keys, or something of that nature.
