Yum hint Another app is currently holding the Yum lock; Waiting for it to exit ...

Using Yum to install the Scheduled Tasks feature, the results are prompt:

# yum-y Install vixie-cronloaded plugins:fastestmirror, Refresh-packagekit, securityexisting Lock/var/run/yum.pid:ano Ther copy is running as PID 25960.Another app is currently holding the Yum lock; Waiting for it to exit ...

It may be that the system is automatically upgraded and Yum is in a locked state.
There is already a Yum process running, kill it with Kill:

# kill-s 9 25960# PS aux|grep yumroot      6744  0.0  0.0 103260   pts/1    s+   14:59   0:00 grep YUMRO OT     25960  0.0  0.0      0     0?        Z    Sep19   0:01 [yumbackend.py] <defunct

I'm sorry, kill can't deal with it.

You can disable the Yum process by forcing:

#rm-F/var/run/yum.pid

Then you can use Yum.
