Hello everyone,

I've just started using OpenProject this week i install it in a fresh centos server and everything it's working.

But the last three days when i'm using it sometimes i get the 503 Service Unavailable.

Service Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

I don't know the problem but i found in my server stats that the cpu uses came to 98% and the ram goes up and down. See the attachments.

The  only solution i'm doing now is restarting the server. any solutions please ?
