The problem happens rarely. I cannot reproduce it.

What I did to get this error: I connected the computer not through the native LAN connector, but through the USB TO ETHERNET adapter. This is my first attempt, so I don't know what is causing the error. I learned the ip address from the list of connected devices to the router. If you do not use an adapter, then trying to connect to the second PC is not a problem.

I left the WinScp window idle for 30' minutes in an open session to grab something to eat. Then, when I returned to my PC and tried to open a new sesion in a new tab, this error printed on my screen.

I have a bunch of subdomains I can access via
/home/apekholdings/pps.apekholdings.com
/home/apekholdings/???.apekholdings.com
etc

When I try to quickly switch between the directories from the bookmarks window by replacing the ??? with the 3 letters, the app hangs. Basically I'm trying to hop 7 layers deep in the hierarchy without navigating the tree every time and then it crashes like this.

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)
Steps I took, just before the error occurred:
I logged into our app server, and system automatically took me to last directory I had been in previously.
I clicked on the right (server) pane header to change the path.
Path navigation dialog popped up, as it has in the past, with current folder path (/misc/.../.../) highlighted.
I was planning to type in the path I wanted to change to /opt/.../... and hit enter, although I cannot remember if I got to type in the full path (just 3 levels) and hit enter, or if it happened when I started to type the path.
That's when the error occurred. I have never seen this error before. />
