Error transferring large file using sftp protocol

Hello All,

I am not able to transfer large file completely (more than 60 MB) through automated SFTP script. It transfers only the partial file (approximately 55 MB) and it stops.

I use "expect" command to transfer file in a automatic mode through script. The file transfer rate i get is around 3 MB per second.

I guess time out is happening some where before the file transfers complete. But i am not able to figure out why it is happening.

Did anyone come across this issue?

Please let me know how to resolve this kind of issue.

thanks in advaince
