Hi Mariel,
if i m not wrong, on the secondary you will see the messages you
mentioned when a checkpoint happens.
What are checkpoint_timeout and max_wal_size on your standby?
Did you ever see this on your standby log?
"consistent recovery state reached at .."
Maybe you can post your whole configuration of your standby for easier
debug.
regards,
