先看看是什么进程占得cpu资源，用show proc cpu或者show proc cpu | ex 0.00 flash卡的告警应该和高cpu关系不大

[Rps-Cheers]

初步查看4900的high CPU问题和Compact flash is not ready这个报错没有什么直接关系。

两个方面：

1、关于Flash的报错：

Error Message： C4K_FLASH-4-COMPACTFLASHNOTREADY: Compact flash is not ready
Explanation：
You may see this message if the compact flash is not inserted properly or if it is removedExplanationwhile the switch is trying to access the flash

Recommended Action:Reinsert the compact flash and retry the operation

2、关于high CPU问题，可以参考如下排查手册
