Help Understanding Log Files

Looking over my log files I have two questions:

1 - Can someone help me understand why it closed with code 12? The script is just calling close, so I want to make sure that all files downloaded correctly.

> 2013-03-27 15:45:18.273 Script: close
. 2013-03-27 15:45:18.275 Closing connection.
. 2013-03-27 15:45:18.276 Sending special code: 12
. 2013-03-27 15:45:18.281 Sent EOF message
. 2013-03-27 15:45:18.288 [Shell] Closing connection.
. 2013-03-27 15:45:18.289 [Shell] Sending special code: 12
. 2013-03-27 15:45:18.291 [Shell] Sent EOF message


2 - I see a lot of these in the log, but don't think it is an error. Is there a qay to suppress them?

12 is EOF signal. There's nothing wrong about it.
