Jupyterhub cpu usage 100%

Hello!I would like to ask, when my jupyterhub worked overnight, which is about 12 hours, its cpu usage became very high, almost 100%. When I restarted jupyterservice, everything went back to normal. I am not sure how my log can help me. Can someone help me solve this problem?

Does anyone have a similar situation?

We’ll need more information before we can guess what the problem is. Ideally can you provide instructions so someone could reproduce your deployment and problem, starting from scratch?

I was trained by: jupyterhub-the-hard-way/installation-guide-hard.md at 35ddfb49ad81771551c6549696ccec960564d5e4 · jupyterhub/jupyterhub-the-hard-way · GitHub to deploy, completely follow the steps above, After deployment, they can be used normally, but the cpu usage is very low at first, and after about seven or eight hours, as shown in the figure above, it becomes very high. What is the problem?

It may be useful to attach py-spy to your JupyterHub process, which can help identify what it’s doing.
