The server is having trouble keeping up with your statistics processing schedule. You should increase the time between statistic generation, or upgrade the server.

If the server is overloaded and does not have sufficient CPU resources cPanel will pause statistics processing because it can be a very CPU intensive process. This helps to avoid problems where processing bandwidth data causes the server to fail entirely due to the added CPU load.
While this will help to reduce server failure, the result will be that no statistics data will be available for you to review.
In order to resolve this issue, you must reach out to a systems administrator that has the skills, training, and expertise required to diagnose the cause of the high CPU usage, and then implement a plan to either increase the CPU resources available to the server, or a plan to reduce the CPU usage to acceptable levels.
