>
> By default the page limit parameter is set to -1, which means to assign 1/3
> of Heap space to the LedgerCache. Each LedgerEntryPage is then allocating the
> memory outside the heap (ByteBuffer.allocateDirect()).
> This makes BK to use more memory than the -XmxNN configured setting. Is there
> any particular reason for the LedgerEntryPage buffer to be allocated outside
> the java heap? Could that be changed?
