SFTP hangs after a day or two
Hello-
I'm using Camel 2.2 SFTP component like so:
from(sftp://user@ftpserver:22/OUTBOUND?delay=60000&delete=true&localWork
Directory=\\\\3050-b\\Intranet\\adp\\employee\\tmp&password=secret)
.routeId("sftp")
.log("Moving file ${file:name} to localWorkDirectory.")
.to("file: \\\\3050-b\\Intranet\\adp\\employee");
Once a day, files are posted to the ftp server which the above route
will transfer to a local server. This runs fine but then hangs after a
day or two. This is a tough problem since I cannot reproduce it in
development to try out various uri options. After taking a look at the
uri options for the sftp component page on the wiki, I noticed the
"disconnect" option. It says it will disconnect right after use. This
seems it might work but I don't fully understand how connections to the
ftp server are maintained within the Camel. I would imagine they are
fault tolerant.
Any thoughts on why this route may be hanging? I've double-checked that
we are in fact using commons-net-2.0 as suggested in another users
mailing list post.
Any ideas?
Thanks,
Russ

Hi
Adding the "disconnect=true" option to the sftp uri seems to have solved my issue.

Hi
Camel 2.4 has better re-connect logic with the FTP components.
So wait for that release.
And yeah use the disconnect if you are not constantly polling from the remote FTP server.
Then its a better chance the FTPClient is capable of connecting when you need to poll.
