"Closed connection unexpectedly caused by winsock error 10061 on Win2008 R2

Hello, PostgreSQL-development.

This week our support had two complains on a very similar situation.
After several minutes of work clients got "server closed the
connection unexpectedly. This probably means the server terminated
abnormally before or while precessing the request."

One client's environment uses MS Windows Server 2008 R2 and the other
one uses Windows 7.

In the log there are plenty of
"unrecognized winsock error 10061"

Googling gave me some more results on this, e.g.

Do we aware of such cases? Do we have any straight solutions for them?

I've attached the log. It's in German I think.
