yaST2 locked up after first Installation

I just installed 11.1 Version, and after reboot etc, tired to use yaST2 to install few programs, I am getting this message:
" system Management is locked by application pid7119(/usr/sbin/packagekitd) close the application before trying again."
There is a file by that name but no application is running! further if it is running in an invisible in the background how you would close it?
Any idea how to overcome this? or get around it!

I just enter a console and type

kill 7119

or if that won’t work

sudo kill 7119

Sometimes takes a few goes, but you’ll get rid of it.

You apparently can also do it through top.

Thanks for the response, I followed the procedure, but as one is closed, the next one comes up!
