Process.Cmdline() is rising memory on windows

[hoaidanh]

There is my code

processArray, err := process.Processes()
for _, item := range processArray {
		
		cmd,_ := item.Cmdline()  //rising memory
		//do something
}

I check memory, it rising memory so fast, and item.Cmdline() is the cause, you can see in the picture
