Description

SFTP Processors include a Connection Timeout property, which applies to the initial socket connection, and a Data Timeout property, which applies to subsequent socket read and write methods.

The SSHJ library also has a Transport Timeout setting that controls how long SSH operations should wait before considering the operation failed. The internal default value is 30 seconds, and setting the timeout properties on the SSHJ SSHClient object does not change the Transport Timeout setting. The SFTP Processors should be updated to apply the Data Timeout property to the SSHJ Transport Timeout setting.
