yum 更新时出错

CentOS 6.3

最近我在 CentOS VPS 上运行时出现以下错误yum update：

[user@foo1 ~]# yum update
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile

我已经尝试过yum clean all，但这似乎没有帮助。 VPS 一开始就没有很多内存，但我并没有看到它的值很低：

[user@foo ~]# free
             total       used       free     shared    buffers     cached
Mem:        262144     109904     152240          0          0          0
-/+ buffers/cache:     109904     152240

如果我重新启动系统，它就可以正常工作（一段时间......然后问题在几个小时后再次出现）。

有什么想法吗？我可以采取什么措施来解决这个问题？

我在这里找到了答案：http://blog.aditech.info/2012/05/fix-threaderror-cant-start-new-thread.html

简而言之，盒子上的可用内存不足。禁用最快的镜像插件解决了该问题。
