> Camel FTP component fails to process multiple files at once from a specified
> folder (let's assume the folder is /in).
> When the consumer connects to a ftp account and finds a list of, let's say, 3
> files, it will try to retrieve them in parallel but this is not handled
> properly.
> As you can see from the below FTP server log, this is what Camel FTP does:
> - it changes the current directory to /in
> - retrieves the file
> - it changes the current directory to /
> - the second (probably) thread changes the directory to /in
> - retreives the second file
> - the first (probably) thread sends a delete command but it sends it as if it
> were in the root folder but it is actually in the /in folder
> - the FTP gives an error that the file doesn't exist
> - somehow the FTP Component blocks itself on the first file...
> See my comments in the following log starting with *****

> A workaround that seems to work is to use the maxMessagesPerPoll=1 option.
