why

If you have some memcached servers and want to transition to couchbase, you'll get into trouble because moxi, the couchbase memcached proxy will try to bind port 11211. I didn't find any way to change this port in the official documentation.

How

Finding out how moxi comes to life

ps tells us moxi is spawned by an erlang process, the main couchbase one, ns_server.
