Could not receive data from client: Unknown winsock error 10061

Hi,

the error message of the subject is my big problem, log entrys:

2010-02-24 12:22:25 LOG: XX000: could not receive data from client:
Unknown winsock error 10061
2010-02-24 12:22:25 LOCATION: pq_recvbuf, pqcomm.c:738
2010-02-24 12:22:25 LOG: 08P01: unexpected EOF on client connection
2010-02-24 12:22:25 LOCATION: SocketBackend, postgres.c:307

After this messages our WebSphere Application Server 6.1.0.9 crashs, with
Database Timeout.

I spend many time on google and the postgre manual and found some possible
problem causes, but no one helped me.

The following link describes my problem and including a patch, but the
link seems to be down.
