Thanks for you reply! Server and the client conect with the same CISCO switch. We have checked the switch ,but no CRC error occur. This issue always occur after we reboot the server and the postgres service just become ready statu for serval several minutes. It is possible that server's performance cause the issue (server is too busy on that moment) ? Thank you!

Is there any NAT between client and server? What sort of network connects the two? Is there any packet loss on the network? Is there any sort of firewall on or between the client and server? -- Craig Ringer -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
