The reason is that the test failed waiting on below LOG:

### Reloading node "standby1"
# Running: pg_ctl -D

/home/ec2-user/bf/root/HEAD/pgsql.build/src/test/recovery/tmp_check/t_040_standby_failover_slots_sync_standby1_data/pgdata
reload
server signaled
timed out waiting for match: (?^:LOG:  slot sync worker started) at
t/040_standby_failover_slots_sync.pl line 376.

Now, on standby, we see a LOG like 2024-02-22 10:57:35.432 UTC
[2721638:1] LOG: 00000: slot sync worker started. Even then the test
failed and the reason is that it has an extra 0000 before the actual
message which is due to log_error_verbosity = verbose in config. I
think here the test's log matching code needs to have a more robust
log line matching code.
