The etop output doesn't show any Erlang process consuming an outrageous
amount of CPU, while one of the threads in the strace output appears to
be stuck in a loop. This points to a problem within the Erlang VM rather
than the Erlang code being executed.

Try upgrading to the latest version of Erlang, and also try downgrading,
in case this is a problem that was recently introduced. Also try running
with defaults in rabbitmq.config.

If the problem persists then it may be worth asking over at the
erlang-questions mailing list.
