This topic describes the cause of and solution to the issue that the logic for collecting statistics on the system load is affected by the container resource statistics enhancement feature developed by Alibaba Cloud in Alibaba Cloud Linux 3 with kernel version kernel-5.10.60-9.al8. The container resource statistics enhancement feature collects statistics on the system load in containers in rich container scenarios.
Problem description
If you run the top command in the operating system that does not have load but meets the following conditions, the displayed average load is always greater than 1:
Operating system: Alibaba Cloud Linux 3
Kernel version: kernel-5.10.60-9.al8
Cause
Due to the statistical issues of the container resource statistics enhancement feature, errors occur in the statistical logic of the system load. As a result, the value of the system average load (load averages) is always greater than 1 when the operating system does not have load. This flaw only causes errors on the statistical logic of the system load. The system load does not increase and the features of the system are not affected.
Solution
Run the following command to disable the container resource statistics enhancement feature.
After you disable the container resource statistics enhancement feature, the statistics on the system load are properly displayed and the existing features of the system are unaffected.
sudo sh -c 'echo 0 > /proc/async_load_calc'
