LibreNMS does not have any long lived processes. If rebooting the server helped, it was either a coincidence or not related to LibreNMS.

HI

But in the event log usually their will be logs if email transport is triggered, but now we dont find any logs about the Transport. We can see only the Alert trigger log

But if we reboot we can see the logs and transport trigger working

Thanks
