linux运维 - 请问Linux系统有大量的migration和watchdog进程该如何解决？

Question

系统：centos6.5
内核：2.6.32

运行的是单节点ceph集群，top发现有大量的migration和watchdog进程，只有重启才能消除。
有哪些可能导致这种现象？求解决方案。
谢谢！

Answer 1

Normally, there is one core, one watchdog, and one migration. If you have 8 cores, then there are 8 of each. This thing is used to monitor the system. It usually doesn’t take up any resources, so just don’t worry about it
