Hi,

I'd appreciate any assistance someone could provide to parse the following log entries.

I've included the Log File and WinSCP.ini file below.

If that does not help, come back.

Also, are you able to connect with any other SSH client?

The issue I have is that this situation occurs from time to time.
I'm stuck using WinSCP 4.3.5 and on the Connection tab I do not have the option to un-select "Optimize connection buffer size".

I'd really appreciate any assistance/direction you could provide with modifying the parameters in the WinSCP .ini file I included in my initial post.

There's no way to turn off Optimize connection buffer size in 4.3.5.

If I upgrade to a newer version of WinSCP do I need to back up the contents of my current installation before upgrading?

No.

Martin, I upgraded my client from 4.3.5 to 4.3.9, however the GUI did not change.

Please see the attached screenshot.

Sorry I was wrong. The Optimize connection buffer size is always off since 4.3.3 (until 4.3.9). So your problem is not related. I do not know what else to suggest. Sorry.
