[users@httpd] mpm-event not killing child process

Hi,

Server Version: Apache/2.4.25.

I am not able to figure out why apache parent process not killing childs
when there are so many idle workers. Please help me to understand this

mpm-event configuration:

<IfModule mpm_event_module>
        StartServers                     2
        MinSpareThreads          32
        MaxSpareThreads          96
        ThreadLimit                      64
        ThreadsPerChild          32
        MaxRequestWorkers         480
        MaxConnectionsPerChild   0
</IfModule>

status output:
   5 requests currently being processed, 507 idle workers
