Abnormally high CPU usage

[rayn316]

System information

Geth version: v1.101304.2 OS & Version: Linux Commit hash : (if develop)

Expected behaviour

The node request is normal, and the node situation is also normal during the rpc request.

Actual behaviour

After receiving the request, geth uses very high CPU, causing the program to be killed and the data to be corrupted after restarting the node. The situation is still the same after trying 2 times, version includes: v1.101305.0-rc.2

Steps to reproduce the behaviour

It is suspected that the ws request caused the CPU memory abnormality
