Mule - Stopping inbound endpoint until outbound endpoint connector is available

Question

I've given my mule config below and I use mule 3.4.0. When my activemq goes down the ftp endpoint reads the inbound files and tries to start the jms connector and I get the follwing error. JMS reconnect doesnt happen until I restart mule. Please help. Thanks

Starting/stopping endpoints in case of errors, is not a typical pattern used in Mule.

Instead use a message processor like until-successful to keep retrying the jms:outbound-endpoint interaction until it succeeds.
