There is a store_dir_select_algorithm directive, which defaults to
"least-load", but can be set to round-robin. In other words unless you
have a fairly similar amount of big and small objects entering your
cache, the aufs cache_dir is going to be the least loaded on occasion,
and will take some of the smaller objects.

There was a discussion a few weeks ago about a min-size cache_dir
option, that also has a possible explanation of what you are seeing:
