Hi guys,

hope this is the right corner to post this issue as it's difficult for me to pin down the origin.
Basically I am running a Centos 7 box and lately i get notificartions of httpd unavailable and apache shutting itself - rebooting every day / sometimes several times a day intervals of about 3 hours and down-time of about 30 min.

I post here some log messages:

Notification: The service “httpd” appears to be down.

Reason: Service check failed to complete. Unable to connect to port 80 on Connection refused: Died

It seems to me a connection to the Apache service - so let me know if this post is better suited in the Apache category of the forum.

The server is no again running stable again since the latest log notice above.

I also noticed when I checked the server and WHM interface after the failure notice, that all services where up and running (service status).

Any advice would be welcome.

NB: I ran some EasyApache updates and will monitor if the issue still persists.

Hello @samlar,

Can you confirm if any third-party Mod_Security rulesets are enabled on this server? Do you notice any output to /usr/local/apache/logs/error_log prior to the times it's reported as down?

Thank you.
