This might be due to the system allocator you are using (e.g. `jemalloc` for example). Often as a performance optimization such allocators will not return memory to the underlying operating system but rather keep it in allocator specific free lists Maybe you can run some sort of heap profiling tool to see if you can see where the memory is being held and what allocations are still allocated (I have heard good things about `heaptrack` for example, and I have also used the `Instruments` tool on MacOSX to track allocations)( -- This is an automated message from the Apache Git Service.
