site getting down every 1-2 hours sharing nginx & httpd status & log

[arjch]

Hi,

My site is getting down after every 1-2 hours I have checked all the services, everything is working fine on service status window. I am using custom build of apache-nginx. The problem only goes on restarting the server. But its a temporary solution.

Any help appreciated.

Hello,

Any help appreciated.

The lines you've posted do not explain reasons of the issue, as well as they do not prove the issue. Since Nginx and Apache are reloaded together, then it is probably Directadmin restarts them to apply requested changes. You might check logs in /var/log/directadmin/ for other possible clues.

 

[arjch]

directadmin error log only shows this:

2025:03:16-20:26:18: File ./data/users/admin/domains.list has been written to after this process read it. Not going to overwrite it. This read timestamp=1742066738, before-write timestamp=1742153178

 

[zEitEr]

Probably not related, or at least does not give any clues yet. You will probably need to search through all other logs under /var/log/ for entries around the time of the webservices reload.

I have changed the "ServerName to-server-domain" now its been 3 hours without down time, may be that was the issue, dont know no major error was reported in the logs.
