long lost child came home! (pid process-ID)

After restarting the server with graceful, the control process terminated a process that was not to be monitored.

Error level: warn

(S) The control process uses the scoreboard file to manage the status of the server process. If the process terminated after restarting with graceful does not correspond to the managed process, this message will be output.

(O) Revise according to the cause due to which the terminated process does not correspond to the process to be monitored by the control process. For example, the gcache server is a process that is not to be monitored by the control process. The server process is a process monitored by the control process, and if this message is output for the server process, the server process may have been outside the monitoring range of the control process for some reason.
