PHP-FPM Process not dying

[Satheesh M]

Hi Guyz,

I have php-fpm with php 5.4 - 30GB RAM 16 Cpus .. 

pm=dynamic

pm.max_children = 400 
pm.start_servers = 10  
pm.min_spare_servers = 10  
pm.max_spare_servers = 25 

pm.max_requests=0 (unlimited)

It handling the request fast but after reaching the pm max php-fpm is becoming dead .. 

The process is showing in running state and changing to idle but not dying it waiting for many hours .. after restarting the service only it getting clear .. how to fix this issue ..

The process creating but dying .. soon it reaching the limit ..

Try :

pm.max_requests=10

as 0 means unlimited, which can lead to no process recycling and potential memory leaks etc

for eg: if i give pm.max_requests=10 ... will it only handle 10 request per second ? 

i am getting 0.5 million request per day approx ..

If I’m not mistaken, pm.max_requests will define how many requests should a process handle before it’s killed off. 

Also if you have constant load and need quick  response, you might want to try going with static.

 after reaching the pm max php-fpm is becoming dead

which setting are you talking about?

Define "dead".

pm.max_requests defines max requests per process instantiation. Set it to 20000 and see how it goes.
