The soft limit is the value that the kernel enforces for the corresponding resource The hard limit acts as a ceiling for the soft limit an unprivileged process may only set its soft limit to a value in the range from 0 up to the hard limit. So in order to make the change in fds count without any error we should inform the user to make the process have CAP_SYS_RESOURCE capability in order to set the hard limit.
