Issue Nginx problem, website crash every 30 mins

[wazoomstudio]

Hi everybody,

Since 2 week each 3 /5 days websites crash (3 differents website with 2 ips), nothing abnormal on the logs. All services running. PHP under FPM Apache. After restarting server all was working.
This night get a new alert, and another and another. et like 7 crash from this morning.

I try to find a solution and switch from apache to Nginx on my UI. Things i notice since that changes
- Immediatelly website was up
- Only one website now bug and the 2 other not crash
- The downtime is only 1/3 minutes (before was + 15 mins)
- I also records some nginx error. Tryin to search on forum but dont find anything revelant.



Do you have any idea, where i can looking for to solve that issue ? Can i solve these alerts ? Maybe wich logs should i check ?

Thanks a lot !
