Yes, I did add entries by hand at first but then removed them and
used adduser command, then went back and cleaned it up by hand.

I ran 'getent passwd' and it database dumped the passwd file,
so it seems.

No, I did not but I did use google search and there were complaints
about it and various responses but none that solved the underlying
issue. That is why I experimented and found out that it was somehow
FedoraInfinity that was causing it - albeit maybe only a symptom.

Can you give me a link to Bugzilla - it's been many years since
I have gone there. But even if you do, I am not sure what to
do... just post a bug report like I described what I did in this

Anyway, I thought for SURE it was caused by ISPConfig because it
was there that I experienced all sorts of wierd stuff - I lost
the use of setroubleshoot/sealert (runs high CPU), and then could
not get the GDM login screen - so I basically went through and
started removing all the packages including ISPConfig that I added
one by one so that I knew there was nothing left that I did not
install myself.

At that point - I decided to dive into /etc/gdm and /usr/share/gdm
and so now I *think* it's that newfalngled FedoraInfinity theme
and it means what it means - the gdmgreeter runs to fedora infinity
at high CPU loads! :P
