How the duplicated edis occur ?

after we use idempotent in option of camel----file component, the gluster won't get dead again, that doesn't mean no crash  of  edi-grabbing any more. Sometimes (though only little) , because of no read lock for table, 2 more smx will get the same edi, whick will cause  duplicated edis.

All the grabbed edis won't be deleted from in-process repository and gluster untill the whole car-middle-png flow is done.
