Thanks, the wal_sender_timeout setting was the culprit!
A bit hard to find that it influences a ping at half its interval time though.

Status messages are also sent in response to sender pings that is controlled by that variable. Wal sender sends a ping after a half of that setting since the last status message to request walreceiver to send a response. > checkpoint_warning = 93s > max_standby_streaming_delay = 130s > max_standby_archive_delay = 45s > wal_receiver_status_interval = 600s > wal_receiver_timeout = 1200s > wal_receiver_timeout = 65s > recovery_min_apply_delay = 600s > > The random values were to see which setting is limiting if I got above the 30s limit. regards. -- Kyotaro Horiguchi NTT Open Source Software Center |
