Why does Apache do graceful restarts?
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.
