I'll assume you're on linux, in which case try setting those values with sysctl like so: Edit /etc/sysctl.conf. add these lines at the bottom: net.ipv4.tcp_keepalive_time = 300 net.ipv4.tcp_keepalive_probes = 2 net.ipv4.tcp_keepalive_intvl = 30 Then run "sudo sysctl -p" See if the changes took effect: sysctl -a|grep keepa -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
