After waiting for 7 hours, it works normally now, but the cpu cost is still high.

[yanliang567]

I guess the milvus is building index that's why the cpu cost keeps high at this moment. If you have milvus metrics, you can check and confirm it. Before that we can see there are Timestamp lag too large errors, i think that was you had too many insert/delete requests that milvus cannot handle it in a short time.
As it was recovered now, i think we shall do nothing for now.

My total data is around 10G, and when do restart, I am sure that I didn't send any insert or delete request, why it's cpu cost so high? And does it normal that it cost so much time for hours?

After restarting, the log didn't show error, but if I try to search or delete , it shows error below.
