gnome daemons left running at logout

[James Bardin <jbardin bu edu>]

Hello,

We recently started using CentOS 5 (RHEL5), with gnome 2.16 in our labs.

I've noticed that sometimes after logout; gnome-vfs-daemon, 
gnome-volume-manager, gnome-power-manager, and gconfd may continue 
running under the last user's uid. The next login gets new daemons (even 
if it's the same user), and these processes start to build up. 
Basically, if they don't die soon after logout, they never die.

I can write a cron job to clean these out, but is there some 
mis-configuration causing this?

Thanks
