Possible Bug

Hi,
Thank you for sending me the links.

For GDP-11, we are using systemd 229, which already
included the mentioned patch codes to systemd. But it was
noted that the fix can only reduce the chances of encountering
the problem and that the problem still persists.

>From the thread, it is mentioned that the unified cgroups are being
actively worked on, but the 'perfect solution' is in the works:
https://github.com/systemd/systemd/issues/317#issuecomment-136483338

Some of the commenters mentioned reverting the systemd back to a previous
version which didn't have this problem, but did have a racing condition
https://github.com/systemd/systemd/issues/317#issuecomment-123195295

And a possible workaround for this problem
https://github.com/systemd/systemd/issues/317#issuecomment-115656106

And it seems to still be around by the end of last year :
https://bugzilla.redhat.com/show_bug.cgi?id=1394937

What is everyone's opinion on what we should do in this case?
Should we revert the systemd? Do a workaround? And if we do a workaround,
should we apply it to all Genivi apps?

Thanks in advance for your inputs!

Best,
Vy
