Grafana firing alerts of last 1 month now

I think the firing of alerts is so random. Last 1 or 2 weeks alerts i am receiving now. It is so strange. And sometimes even if memory or cpu is high, in the grafana dashbaord it shows firing, but never get email. May be if i wait for 1 week then i get the email lol.

Any ideas why this is happening. It is so inconsistent in firing the alerts.
