> If PFC is disabled, when the store cursor checks limits, it checks only the
> memory percentage of its own MemoryUsage and compares it to the high water
> mark. Otherwise if PFC is enabled, it checks whether the MemoryUsage is
> "full" but the "isFull" method also checks its parents.
> This issue arrises when you have memory limits set on queues higher than the
> overall system limit, as well as if you have multiple queues who's memory
> limits combined are higher than the overall system limit. These settings must
> be taken into account.
