Hi,
Parent httpd process isn't spawning a new replacement child in a timely fashion,
after MaxRequestsPerChild has been hit and the child worker httpd has
exited with the below settings:
Timeout 70
KeepAlive On
KeepAliveTimeout 60
<IfModule mpm_worker_module>
StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 10000
</IfModule>
Please let me know if any modifications required in httpd.conf file
settings to create new child process
Thanks & Regards,
matty
