The problem is caused by the Cgroups. 

Uninstall Cgroups and everything will work just fine.
What are Cgroups?Cgroups (control groups) are a Linux kernel feature that limits, accounts for, and isolates the resource usage (like CPU, memory, I/O, etc.) of collections of processes. They are often used in containerized environments (like Docker, Kubernetes) or to manage resources in multi-tenant servers.How Cgroups Could Cause the IssueIf cgroups are configured to restrict the resources available to the PHP process, they could be affecting the execution of thecommand. For example:

• CPU Resource Limits: If the process running the PHP script is restricted in terms of CPU resources, it may not be able to execute system commands like

  cat /proc/loadavg

  .
• File Access Restrictions: Cgroups could potentially restrict access to certain files like

  /proc/loadavg

  , which would prevent PHP from reading the file or executing shell commands that interact with it.
• Process Execution Limits: The cgroup could limit the ability to spawn or execute new processes (like using

  shell_exec

  ). This could prevent PHP from running shell commands like

  cat

  .
