The CloudLinux LVE manager has an option to notify either a user or an admin if their account exceeds their resource limits in a specific time period. However, with improper settings, it can create a false-positive e-mail suggesting that all users are exceeding their limits.
In WHM, CloudLinux LVE Manager under options there is a setting for LVE Faults Notifications that allows you to select the type of faults, who to notify, how often to notify them, and when to notify them.
If the Minimum number of Faults to notify user option is set to 0, it will send out a notification even if that user did not exceed their resources. To resolve this issue, make sure to set the minimum number of Faults to at least 1 for user and admin.
