SOLVED LFD Excessive Resource Usage - Normal for PHP-FPM?

[ItsMattSon]

Hi guys,

I know this one is probably majority third-party so perhaps better suited on the ConfigServer forums but if anyone has run into this running cPanel and php-fpm and knows a little bit about it, it'd help. Of course, I don't really expect a huge amount of replies here so no hard feelings if I get no feedback :p

Just curious if anyone else receives a lot of emails from LFD regarding 'excessive resource usage' from php-fpm where command line is 'php-fpm: pool site_com'

Time: Wed Feb 8 22:19:14 2017 +0800
Account: site
Resource: Virtual Memory Size
Exceeded: 547 > 256 (MB)
Executable: /opt/cpanel/ea-php56/root/usr/
sbin/php-fpm
Command Line: php-fpm: pool site_com
PID: 26852 (Parent PID:17641)
Killed: No

I know I can set the PT_USERMEM value higher than the default 256MB to never see these particular emails again and I know I can disable it even, but it serves a purpose enabled and left at 256.

Anyone know why php-fpm is going above? Or how to diagnose that? Or is it pretty normal? (if it is, I suppose I could deal with that)

I find this quite normal, if the thread isnt overloading the machine there isnt much to do except to tune PT_ or FPM.

 

[ItsMattSon]

Yeah, I think you might be right there @SB-Nick.

Mind if I ask you how you'd personally handle it? Would you raise PT_USERMEM to 768MB or would you add that 'php-fpm: pool site_com' Command Line to csf.pignore?

 

[SB-Nick]

I personally pignore it on medium to heavy boxes.

So, in the end I went with adding the Command Line of two that were hassling me every minute or so as I didn't thing disabling PT_USERMEM was a good idea or raising the value to anything higher.

I know this line can be faked by exploits but I guess there's no better way to go about it, really.

cmd:php-fpm: pool site_com
pcmd:/opt/cpanel/ea-php56/root/usr/bin/php /home/site/public_html/bin/magento *

And as long as I put those together correctly, that should be the last I see about PHP-FPM pool for that site and Magento's cron jobs. Thanks for the help!
