Hello,
My server down and I check apache log and recived this:
[Fri Jan 30 05:27:48.795468 2015] [mpm_event:error] [pid 15710:tid 139807952553920] AH00485: scoreboard is full, not at MaxRequestWorkers

[Fri Jan 30 05:27:52.800239 2015] [mpm_event:error] [pid 15710:tid 139807952553920] AH00485: scoreboard is full, not at MaxRequestWorkers

My server configuration is:
Nginx_apache
Apache 2.4.10
php_fpm 5.4

Apache configuration in /etc/httpd/conf/extra/httpd-mpm.conf is:
<IfModule mpm_event_module>
StartServers 6
MinSpareThreads 32
MaxSpareThreads 128
ThreadsPerChild 64
ServerLimit 16
MaxRequestWorkers 1024
MaxConnectionsPerChild 10000
</IfModule>

I checked other thread and set the following in my /etc/sysctl.conf and reboot server.
kernel.msgmni = 1024
kernel.sem = 250 256000 32 1024

But after a few days I get "scoreboard is full, not at MaxRequestWorkers" error in apache logs and my server down.
What to do?
Why my server down?
Thank you

Hello,
I get error in apache yet and my sites could not be loaded.
server reached MaxRequestWorkers setting, consider raising the MaxRequestWorkers setting

In this case,I restart apache and nginx services but my sites could not be loaded until I restart php-fpm54.
What to do?
Why this problem can not be solved?
Thank you
 
Hello,

It seems I've already suggested (in another thread of yours) that you should check and optimize PHP/MySQL stack, mysql indexes and queries.
 
Hello,
I change apache from event mpm to worker mpm and my server problem solved.
