Gordon,
Could you try:

erlang:process_info(list_to_pid("<0.16614.32>"), [messages,
current_function, initial_call, links, memory, status]).

in a riak search console for one/some of those mailboxes and share the
results? I am curious to see if you are having the same systemic
memory consumption I am experiencing.

Gilbert
