-bash: child setpgid (560 to 560): No such process

Hi All,

I am getting the error message above every time I try to execute any command. For example:

[~]# ls -al /boot
-bash: child setpgid (560 to 560): No such process

All I did was run "yum update" and downloaded all the updates and installed them. Am I not supposed to do that after installing a distro?

Thanks,
