Linux yum错误解决方法

今天在linux中使用yum时出现如下错误：

Loaded plugins: fastestmirror, security

Existing lock /var/run/yum.pid: another copy is running as pid 4733.

Another app is currently holding the yum lock; waiting for it to exit...

The other application is: yum-updatesd-he

Memory :  22 M RSS (249 MB VSZ)

Started: Fri Jul  6 12:18:29 2012 - 53:47 ago

State  : Sleeping, pid: 4733

关机重启后也没有解决，后尝试删除yum.pid文件，并重启yum服务后OK，具体命令如下：

rm -rf /var/run/yum.pid

/sbin/service yum-updatesd restart
