On publisher it shows me "terminating walsender process due to replication timeout" But the problem is that this message is occurring 3 or 4 times a day only. It tries to send data, gets a timeout then shows the message. Then it waits a long long long time to try again, I don´t know why. wal_sender_timeout is configured to 1 hour Yesterday I had 4 messages of timeout on server log but no data were replicated. So, it tried just these 4 times ? -- Sent from: https://www.postgresql-archive.org/PostgreSQL-general-f1843780.html
