Time change and Email alert sending issue

[Prakash_Chhetry]

Hi @laf ,
Is there any possible solution for the above issue?
I tried to follow the previous solution that you have posted.

LibreNMS not sending email alerts

We run locking on things like alerts.php so if you’ve run it whilst it’s already going this might be why. It will run every minute so take a look at your process list for alerts.php, if none are running and it’s part way through the minute, run ./alerts.php -d You can also check for any files called: .*.lock, if you find them and the date / time is old, try removing the file.

In the above link do we need to delete any of the *.lock file . I can see the composer.lock file here in my case.
