4.3.2.MGBL 5.1.3.BASE

Description (partial)

When the sftp file transfer of file greater than 1 GB is initiated from the client device, there occurs a rekey process in the underlying ssh session. This error is encountered due to an issue with this rekey process.

Symptom:
While transferring file > 1 GB size, the file transfer stops at 1 GB and does not proceed any further.

Conditions:
This issue is hit only when sftp is run in the client device. When sftp file transfer is initiated from server, there is no such issue and the entire file which is greater than 1 GB will be transferred seamlessly.
