How turn off the output of the reaper handler log

[93910676wangd]

Hello, I am currently facing a problem. pgpool runs in Docker and upon reviewing its logs, it is discovered that there are a lot of logs related to reaper handler. How can I turn off the output of the reaper handler? Please confirm and answer, thanks.

• Pgpool version: 4.4.3

• sample output log

• Pgpool.config (log section)

@93910676wangd Sorry for the late reply.

The following log messages appear when a child process exits due to settings (e.g., child_life_time or child_max_connections) . This is the normal behavior.

reaper handler
reaper handler: exiting normally

If you want to turn off the output of the reaper handler, you need to set log_min_messages to fatal or panic.
