The FTP consumer (with the same endpoint) does not support concurrency (the backing FTP client is not thread safe). You can use multiple FTP consumers to poll from different endpoints. It is only a single endpoint that does not support concurrent consumers.
The FTP producer does not have this issue, it supports concurrency.
In the future we will add consumer pooling to Camel to allow this consumer to support concurrency as well.
