Dear all, Environement: - OS : Ubuntu 10.04 LTS. - DB: postgresql 8.4. - Connection to postgresql using sslmode = disable
Scenario : 1. I use pgadmin to connect/disconnect to the postgresql server on port 5432 or 2. I use a progam using libpq and make PQconnectdb and PQfinish. Bug: In both cases, the client socket (pgadmin or my program) remains in TIME_WAIT state. I have used wireshark to sniff the TCP protocol. We have at the end of a connection: Client Server ---> FIN,ACK ---> <--- FIN,ACK <--- ---> ACK ---> This ends up in a TIME_WAIT state. The TCP protocol should be Client Server ---> FIN,ACK ---> <--- ACK <--- <--- FIN,ACK <--- ---> ACK ---> I suppose there is a bug in the postgresql server that do not send an ack to the client. Could you please clarify this situation ? I am a bit lost. Thank you, Franck Lefort
