My php-fpm is regularly stopping, how to fix it?

[Aar]

I have the idea that my php-fpm56 on my VPS seems to stop regularly. The memory seems normal, and the load seems to rise to 0.80, after which php-fpm56 suddenly stops working. The sites that use, it will keep loading until I restart the services for php-fpm56. Other sites om php-fpm70 just remain online.

The traffic to my web server does not seem to have increased either. Does anyone have an idea why php-fpm regularly quits? I cannot find a clue as to whether a certain script is responsible for it.

Check your logs for clues.

The problem was existing after i have updates DirectAdmin to the version 1.55.
Now i have installed 1.56. Now i have heard that there's a new feature:

And a bugfix for something else:

Maybe it's a chainreaction?

Maybe is this working?
The memory for my php-fpm is now lower than first.

**Fingers crossed. **

Nope, php-fpm was down again. The memory arounn the moment to goes down is 430 MB.
Is there an option to tweak php-fpm or a possibility to restart the php-fpm?

Can i do something this this feature?

I see a lot of threads:

php-fpm56 php-fpm56 (pid 12073 14634 14729 14731 14733 14735 14737 14739 14741 14743 14745 14747 14749 14751 14753 14755 14757 14759 ) 227.8 MB

Check out /usr/local/php56/var/log/php-fpm.log, your max_children limit may be reached, which would cause your websites to be unavailable, even while php-fpm56 is still running. If you have enough free RAM available, you could consider increasing the pm.max_children setting.

I think it's solved....

I've installed newest version of DA 1.56, and i've rewrite the configs.
This bug is now disappeared: https://forum.directadmin.com/showthread.php?t=57670 and FPM is using less memory.

If necessary, I will increase the pm.max_children.
