Maybe you should start by telling us: - your PostgreSQL server version - What platform your server is running on - Your PostgreSQL client driver type and version ( native libpq? pgodbc? jdbc? npgsql? etc) - How you're using the client or client driver ... etc -- Craig Ringer

The connects seem to occur quite regularly every 11 seconds... You might want to configure the log output format to include the IP address/host name of the creator of these messages (log_line_prefix in postgresql.conf, "%h"). Or use a packet sniffer like wireshark. Ciao, Thomas
