[systemd-devel] Perl Net::DBus, org.freedesktop.system1 and inhibitor locks

Hi Lennart,

thx for your answer!

Sorry, I forgot to add information regarding my environment.
I use openSuSE Leap 42.1 with a Plasma 5 desktop.
And at the moment my tests are restricted to run my script and then send
the system to sleep myself - so no other user is involved for the
moment.

Yes, but who or what might that be?
As I wrote above - at the moment I'm the only one using the system and I
have no idea, what component might fiddle with my file descriptors.
Do you have any hint, how I could find that out / debug it?

And there is the fact, that the lock is still in the list of inhibitors.
As far as I understand the docs, the entry should be gone when the fd is
closed.

Bye.
