我发现我的linux服务器的cpu使用率如此之高。请参阅以下内容（ps aux | grep migration）：
root 6 99.8 0.0 0 0 ? S Aug19 48073:37 [migration/0]
root 8 98.0 0.0 0 0 ? S Aug19 47192:14 [migration/1]
root 13 98.3 0.0 0 0 ? S Aug19 47355:41 [migration/2]
root 17 98.4 0.0 0 0 ? S Aug19 47382:40 [migration/3]
root 21 97.9 0.0 0 0 ? S Aug19 47132:16 [migration/4]
root 25 98.1 0.0 0 0 ? S Aug19 47231:45 [migration/5]
root 29 97.5 0.0 0 0 ? S Aug19 46926:30 [migration/6]
root 33 99.8 0.0 0 0 ? S Aug19 48055:06 [migration/7]
我搜索了这个问题，然后找到了https://askubuntu.com/questions/85463/high-cpu-usage-without-a-process-to-blame-what-is-migration-x。这是一个错误??
