Hi Fugelin, This is an interesting bug! I would guess that there's a packet being copied in the cache when it should be reused. The simple cache isn't tested with Arm, and it's really just an example and shouldn't be used for anything "real". If you do figure out the bug, we'd love to accept your contribution!
