That looks fine. Can you zoom in on the GC graph you provided and show us here? It would be good if we could see the pattern and GC frequency across a shorter time period, e.g. an hour or two.
Doesn't look too bad, nor exceptionally frequent, but I can see the base is creeping upwards. There has been some memory leak issues fixed since the release you are running, so I would recommend upgrading to version 5.6.9.
I can see 2.2 GB unrachable objects .. after that. i could see 2.7GB unreachable objects in heap dumps
Sounds like you may be affected by one of the memory leaks that has since been fixed, which is why I am recommending upgrading.
