-------------------------------------
So are you stopping / shutting down your Camel application?
> SFTP sometimes doesn't receive all files
> -----------------------------------------
>
> Key: CAMEL-16692
> URL: https://issues.apache.org/jira/browse/CAMEL-16692
> Project: Camel
> Issue Type: Bug
> Components: camel-ftp
> Affects Versions: 3.7.3
> Environment: I'm reproducing this on my own computer and a SFTP
> server running on a Docker container locally.
> Reporter: Jonas Audenaert
> Priority: Major
>
> I have following Camel route, created by a RoutingBuilder:
> {code:java}
> new org.apache.camel.builder.RouteBuilder() {
> void configure() {
> from("direct:myProgram")
> .routeId("${params.profile}")
>
> .to("sftp://${params.hostname}:${params.port}/${params.directory}?username=RAW(${params.username})&password=RAW(${params.password})&fileName=RAW(\${header.fileName})&fileExist=Fail&disconnect=true&stepwise=false&useUserKnownHostsFile=false&serverAliveInterval=${params.serverAliveInterval}")
> }
> }{code}
> This route is the only one which I place on my CamelContext and than I start
> the CamelContext.
> I'm doing a test on my local machine to send 50 files through this route to a
> remote SFTP server. Most of the time, all files arrive, but sometimes 1 file
> seems to be missing.
> My program doesn't notice the failure of sending. But during debugging I
> found something interesting that happened.
> That one specific file which is missing throws in the camel library an
> SFTPException at the method existsFile (SftpOperations.java:1046).
> The exception contains only reason *4:* message but the exception contains
> another exception. The wrapped exception contain following exception message:
> *java.io.IOException: Pipe Closed.*
> Camel wraps the exception in a GenericFileOperationFailedException and throws
> it to the method which called SftpOperations, GenericFileProducer
> (GenericFileProducer.java:135).
> That exception arrives in the tr/catch block of it and goes to the generic
> catch block.
> In that catch-block the exception is handled by the *handleWrite()* method
> (RemoteFileProducer.java:83) and there it gets interesting.
> In handleWrite() check is performed if the Camel Base Service is in
> stopping() or stopped() state. If that's the case, the exception is only
> logged but not thrown. But isStopped() returns true, so my exception is
> thrown, but my application doesn't receive it, so it thinks that the file is
> transferred succesfully to the SFTP server, but it never arrives.
