Please include the stack trace.
> sftp consumes channels on each cd when directory does not exist
> ---------------------------------------------------------------

> Key: VFS-618
> URL: https://issues.apache.org/jira/browse/VFS-618
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: 2.1
> Environment: all platforms
> Reporter: J. Baier
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> While resolving a FileObject on an sftp target for a directory that does not
> exist on the target, SftpFileSystem.getChannel() is called and while trying
> to cd to the workingDirectory, an SftpException is thrown but the channel
> object is not released.
> This leads to many sftp channels kept opoen on the target system and consumes
> unnecessary resources.
> A simple patch of releasing the channel in the caught SftpException in
> SftpFileSystem line 125 would solve this issue.
