i am having issues tuning apache. My current mpm event configs are
<IfModule mpm_event_module>
ServerLimit 24
StartServers 8
MinSpareThreads 512
MaxSpareThreads 768
ThreadsPerChild 64
MaxRequestWorkers 1536
MaxConnectionsPerChild 5000
</IfModule>
if i continuously press ctrl+r on my site for like 20 sec apache hangs, and i need to restart the server On heavy traffic hours also it happens, usually in a day more than 5 times i am facing a downtime. I am reading forums for tuning apache mpm event but not able to figure out.Can anyone please help on this issue or suggest a change or so in my current setup to achieve max performance without hanging apache. I am using an Amazon m3 large instance with ubuntu
