yum update プラグインエラー？

yumを使おうとすると以下のようなおかしなエラーが発生

# yum install heartbeat
Loaded plugins: fastestmirror
Existing lock /var/run/yum.pid: another copy is running as pid 7592.
Another app is currently holding the yum lock; waiting for it to exit...
  The other application is: yum-updatesd-he

Fedora Core 6でyumが実行できない場合は − ＠ITに従い、下記を実行

# ps x | grep yum
 4024 ?        SN     0:00 /usr/bin/python -tt /usr/sbin/yum-updatesd
 7592 ?        SN     0:00 /usr/bin/python -tt /usr/libexec/yum-updatesd-helper --check --dbus
12234 pts/2    S+     0:00 grep yum
# kill 4024
# ps x | grep yum
 7592 ?        SN     0:00 /usr/bin/python -tt /usr/libexec/yum-updatesd-helper --check --dbus
12556 pts/2    R+     0:00 grep yum
# service yum-updatesd stop
yum-updates を停止中:                                      [失敗]
# chkconfig yum-updatesd off
# chkconfig --list yum-updatesd
yum-updatesd    0:off   1:off   2:off   3:off   4:off   5:off   6:off

ところが下記のように再び同じエラーが出るので、4024（yum-updatesd）だけでなく、7592（yum-updatesd-helper）もkillする必要があるらしい

# yum install heartbeat

Exiting on user cancel.
# kill 7592
# ps x | grep yum
