no response from backend - Mailing list pgsql-general

Hi

I have the windows application works on postgres (ver 6.4) database on suse

In work I recive thies messages ocasionaly, sometimes after 10 minutes or
after 2 houers, no rules.

,,couldn't connect to backend - socket has been closed.''
or
,,no response from backend - socket has been closed''

But I still can ping the server or connect to him by telnet.

What's up?
