Matthew,
To clarify, this happens on all nodes in our cluster (10+ nodes) although the
exact size varies by 10s of GB. I’ve rolling restarted the cluster the last
time this happened (last week) with no significant change in size, although the
output from riak-admin aae-status and riak-admin search aae-status shows empty
after the restart.

Rohit,
If you restart the node does the elevated anti_entropy size decline after
the restart?

mostly bitcask backends (relevant part of config pasted below). Has anyone seen
this before, or does anyone have an idea what might be causing this?
