Why does Apache do graceful restarts?

Question

Why does Apache do graceful restarts? 

Answer

Graceful restarts for Apache are normal and by design for Apache. Some of the common causes of Apache doing graceful restarts are the following:

• Any domain management such as adding or removing domains. This includes main domains, subdomain, addon domains, etc. 
• When the statistic logs are processed. This will depend on the times you have configured in WHM under "Statistics Software Configuration".
• Any Apache configuration changes. This also includes AutoSSL/SSL changes such as installing or removing SSLs. 

Graceful restarts should not impact the server.
