Therefore, there are not available for allocation. How can I fixed it with a pgpool config or can i use pcp command to kill a child or is it possible to kill it by a shell command and then, pgpool recreate one ?

I'm not sure how ps command resuls, but you can kill a child process by `kill -9`
and kiilled the new child process would be restarted by the main process if this 
is running. There is no pcp command to kill children processes
