PHP-FPM keeps turning off on the main domains

Snowlion

I am experiencing an issue with PHP-FPM in the Multi-PHP Manager within Web Host Manager (WHM). When I navigate to the "User Domain Settings," I notice that PHP-FPM is repeatedly being disabled for the main domains, while it remains active for addon and subdomains.


This issue is causing performance problems on the affected websites, as they become slow when PHP-FPM is disabled. When I manually re-enable PHP-FPM, the performance improves, and the sites become fast again. However, after about a day, I find that PHP-FPM has been disabled once more.


Why does PHP-FPM keep getting disabled for the main domains, even after I have manually re-enabled it? No one else has any admin access to the server or cpanel accounts. Thanks.

    Hey there!  I don't have a good explanation for this on my end.  Do you see anything in the Apache logs or PHP-FPM logs that might give more detail on this?  https://support.cpanel.net/hc/en-us/articles/360061253694-Where-are-the-global-PHP-FPM-logs-located

    Nothing obvious. Very occasionally a WARNING saying:


    server reached max_children setting (10), consider raising it

    Hmmmm, that's not very helpful, is it?

    What happens if you run our system status tool?  This may show a LOT of output, but just look for anything related to PHP or Apache:

    curl -s https://ssp.cpanel.net/run | sh

    Perhaps these?

    Hello, 

    I'm assuming since you have these named with the word "old" in front of them, that they are no longer being used?  If that is the case, you should rename them so that the "old" is at the end (behind local).

    So something like: vhost.local.old and ssl_vhost.local.old
    Then rebuild httpd.conf (/scripts/rebuildhttpdconf) and restart (/scripts/restartsrv_httpd)

    If they are still used, then please diff their contents with the defaults. 

    Also please provide the output of: 

    cat /etc/apache2/conf.d/includes/pre_virtualhost_global.conf

    Hello, 

    OK, do you know which MPM you're running with?  (event, prefork, fcgid) That will play a big part of which section in your output (if any) might be involved.

    What about the old files?  Did you rename them, rebuild and restart Apache?
