Hi, I try to configure these 3 parameters to activate keep alive on a sever Postgres in version 14.
tcp_keepalives_idle = 3 tcp_keepalives_interval = 2 tcp_keepalives_count = 30 After issuing alter system set ... command and a pg_reload_conf(); these parameters keep value 0. I also check these OS parameters grep TCP_KEEPIDLE /usr/include/netinet/tcp.h #define TCP_KEEPIDLE 4 /* Start keeplives after this period */ grep TCP_KEEPINTVL /usr/include/netinet/tcp.h #define TCP_KEEPINTVL 5 /* Interval between keepalives */ grep TCP_KEEPCNT /usr/include/netinet/tcp.h #define TCP_KEEPCNT 6 /* Number of keepalives before death */ and sysctl net.ipv4.tcp_keepalive_time net.ipv4.tcp_keepalive_time = 7200 Thanks for helping on this point Fabrice
