> FTP Camel Component hangs upon retrieval of files
> -------------------------------------------------
>
> Key: CAMEL-7149
> URL: https://issues.apache.org/jira/browse/CAMEL-7149
> Project: Camel
> Issue Type: Bug
> Components: camel-ftp
> Affects Versions: 2.12.2
> Environment: Linux. jdk 1.7
> Reporter: Hassan Faouaz
> Assignee: Claus Ibsen
>
> Few our routes hung after a successful connection to a ftp server. After
> performing a thread dump, we realized that most our routes that are hung are
> spinning their wheels while listing the files on the FTP server. We are
> suspecting around the fact that the FTPClient socket timeout is not
> propagating to the camel level that is causing it to stay running.
