Hi, When I change Apache global configuration at WHM Home / Service Configuration / Apache Configuration / Global Configuration I see there is a statement saying "Changes to these settings do not take effect until the main Apache configuration file is rebuilt." But I cannot find an option to rebuild the Apache configuration file. How to do so?

  Hey there! Underneath that line of text, there should be a button that says "Rebuild and restart Apache" Do you not see that option on your end?

  Hi, Thank you. But in my WHM, there is no such a button, see below: -07-03_5-45-21.jpg">83329 The cPanel version shows 110.0.7.

  Sorry I have found the button. It appears after I click "Save" button. However, I change the MaxRequestWorkers to 250. However, after rebuilt and restart Apache, I go to "Apache Status" and find there is totally 256 slots, like below: __________LL_W___________________LLL______________________L__R__ ___________________LLLL______________________LL______________... ................................................................ .......................................................... Why?

  Also I notice a strange thing. Although I have changed Max Request Workers to 250, but in the Apache Status page, I notice that the total count of requests + idle workers are always <= 150, for example: 16 requests currently being processed, 134 idle workers or 10 requests currently being processed, 140 idle workers It seems there is still a 150 limit.

  It's odd that the button wouldn't exist. Can you try running these command to see if they work properly? cp /etc/apache2/conf/httpd.conf{,.bak-`date +%Y%m%d`} /scripts/rebuildhttpdconf /scripts/restartsrv_httpd

  Hi, cPRex, Sorry that I have found the button, it only appears after I click the "Save" button. Now my question is after I change the MaxRequestWorkers to 250, then rebuilt and restart Apache, I go to "Apache Status" and find there is totally 256 slots, not 250 slots, like below: __________LL_W___________________LLL______________________L__R__ ___________________LLLL______________________LL______________... ................................................................ .......................................................... Why?

  I see the exact same thing on my personal machine and a test machine, so it seems like that is normal, although I'm not finding a good explanation as to why. Just above the scoreboard you should see a line similar to this: "1 requests currently being processed, 124 idle workers" What does that say?

  Thank you. The total count 1 + 124 = 125 is a multiple of 25
