I have a DirectAdmin server configure with nginx service as reverse proxy. Everything runs pretty good for several months and years.
Since yesterday, DirectAdmin send me each hour on the 17th minute an email that "The service 'nginx' on server XXX is currently down".
When I check it out it's seems that nginx running good (and maybe has restarted by DirectAdmin).
I check my Crontab and i can't find any task that run at this time. Also i couldn't find any error on nginx error_log related to this problem.
CentOS 5.9 (Final) DirectAdmin 1.44.3 (Latest) Nginx 1.1.10 Nginx configured with several Node.js instances and working as reverse proxy. No changes made recently.
