Bug reference:      5022
Logged by:          Tyler Burd

PostgreSQL version: 8.4
Operating system:   Windows Server 2008
Description:        unkown winsock error 10061
Details:

Upgraded from 8.3.4 to 8.4, and we started seeing hundreds of these messages
in the log file:

2009-08-28 14:58:22 MDTLOG:  unexpected EOF on client connection
2009-08-28 14:59:10 MDTLOG:  could not receive data from client: Unknown
winsock error 10061


I am running numerous Windows Server 2008 servers, but I googled and noticed
some others have had this same problem on Vista.  I'm having so many
connection issues caused by this across my server farm that I am reverting
back to 8.3 for the time being.

My complete environment details:
32-bit Windows Server 2008
PostgreSQL 8.4
.NET app connecting with Npgsql 2.0.6

Thanks!
