<li>The used function Devel::Size::size may crash perl (and FHEM) for

call it for such data structures, but as the problem is not identified,
it may crash your currently running instance. It works for me, but make

<li>To avoid the crash, the size of same data is not computed, so the
size reported is probably inaccurate, it should only be used as a hint.
