[rabbitmq-discuss] Clean up stale connections without restarting?

[Nick]

Some of the clients connected to it quit uncleanly, and seem to have
caused RabbitMQ to leave the connection open.  When the client comes
back online, I now have two connections listed (via rabbitmqctl) to
that IP address but on different ports.  I'm worried that I'm losing
jobs to these zombie connections.  How can I clear them out without
restarting RabbitMQ entirely?
