No. I wish it was that simple but this was a new install and there are
no old processes.

What you see above is an output of the loop I ran to capture the lpstat
command and cupsd to show when cupsd dies or disappear from the list
as lpstat continues to process.

If you noticed at the last line where cupsd was still there and
suddenly disappear and only the cups-polld remaining. The strange
thing is that even with debug2 on, there is no error message reported.

Four identical systems reacting the same way is hard for me to ignore
especially when they all work well in previous version.

Anyway, I think I'm just beating a dead horse so I'll just wait until
someone else experience it...could be a long wait.

Thanks,
