Hi Grzegorz Grzybek,

Thats a nice article and explains well about ftp active/passive mode. 
My only point here is {{tempFIleName}} configuration in URI should not drive socket behavior
as it is happening in my case. It clearly stays that there is a problem in the implementation.

Anyways thanks for your inputs

> So many connections remain in TIME_WAIT state while configuring a FTP producer route
with tempfilename property in FTP producer. 
> Files are writen using producer template.
> Producertemplate.sendBodyAndHeader(producerURI, Exchange.FILE_NAME, fileName) to write
file to destination. 
> Producer URI : {{ftp://<USER@MACHINE_ADDRESS>//?password=RAW(PASSWORD)&binary=true&passiveMode=false&delete=true&pollStrategy=#ConsumerPollStrategy&disconnect=false&tempFileName=/temp/hello.tmp&initialDelay=10&throwExceptionOnConnectFailed=true&reconnectDelay=10&maximumReconnectAttempts=0&maxMessagesPerPoll=100&readLock=changed&readLockCheckInterval=500&readLockMinLength=1&sendEmptyMessageWhenIdle=true}}
> fileName: {{file.tmp}}
> We are writing ~ 2000 files . First files are written to temp directory then moved to
destination. Connections opened for tempfiles are not re used to write temporary files and
we run out of connection after writing 1000 files. 
> Route resumes once connections are released. 
> Is there a way we can  reuse connection to write temporary files also.
> Once tempfilename is removed from the configuration then single connection is used for
ftp transfer.
