Fascinating. There's a deep dip in the dentry_cache - I wonder where all that memory for that particular line has disappeared to. I would have expected the other lines to show a corresponding dip going upwards. So I would suspect a leak in the dentry_cache code in certain circumstances.
Also, the steadily gowing-upwards curves for the rest is disturbing. I don't see any sign of memory being freed-up over time. There should be a point where it stabilises and starts re-using buffers instead of grabbing more and more memory as it requires.
