Re: sftp -> seda yields GenericFileOperationFailedException during GenericFileOnCompletion move processing

[GegeFR <gw...@ericsson.com>]

Hi, 

I'm digging this up but 5 years later I'm meeting the exact same issue.

sftp => seda => anything causes this type of errors.

Anybody has any idea about that issue nowadays ?

RE: sftp -> seda yields GenericFileOperationFailedException during GenericFileOnCompletion move processing

Alleluia !

I had an hunch when i saw that sometimes I had exceptions like :
"SSH_MSG_DISCONNECT: 2 Packet corrupt". So that meant that somehow the
software is sending garbage to the SSH server.

And i found ... Well ... To make it short :
 - The Jsch ChannelSftp is not thread-safe...
 - When introducing SEDA or DISRUPTOR we add asynchrous behaviors and thus
try to do concurrent file operations...

To validate I copied "org.apache.camel.component.file.remote.SftpOperations"
into my own sources and added the synchronized keyword in from of every
public method and now it works perfectly, no more exceptions.

So I have now my workaround ... Is someone able to elaborate a proper fix
with only the necessary and smart synchronisations ?

Hi,

the same issue exists on 

sftp/file => disruptor 

It seems something with the BatchConsumer (file). My current "bad solution" to use wiretap to leave that processing.
Would be great to hear a better solution.
