ecli faield: memlock Expand to unlimited

[00032118]

When I used ecli to load the BPF program into the kernel, I found that the memlock was insufficient and failed. During the process of solving the problem, I found that ecli seemed to automatically expand the system's memlock. After expanding it once, reducing it through ulimit -l did not work. Please tell me. Is this a bug? Why is there such a mechanism?
