Subject [jira] [Comment Edited] (CAMEL-8860) Too many connection in TIME_WAIT when tempfilename is set in the FTP producer URI.

-----------------------------------------------------------------

Issue was with endpoint URi which was changing with every message transfer and forcing camel
to create a new connection for every changed URI .We have changed the configuration. Taken
out tempFileName from endpointURI and setting it as header in Producer template. With this
approach uri remains static for each file transfer.

> 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.
