Error notifying Hub of activity

[antonvorobets]

Hi,

I have a sudden issue with a user pod not scaling down automatically. It seemed to run fine for some weeks, but now suddenly this issue appear.

The cluster runs z2jh 3.3.8 with fairly standard configuration. Any ideas on how to fix this issue?

Om that jupyter server failing to report activity, what version of jupyterhub and jupyter_server is it running?

[antonvorobets]

jupyter_server v2.14.2 and jupyterhub v5.2.1

what are the logs from the hub surrounding this event? Do other things involving requests to the Hub work, e.g. logging in and making requests to the server (launching JupyterLab, notebooks, etc.)?

The error appeared after a user node failed to spawn. How that happened, I don’t know.

The user’s logon stayed like this for at least 1.5 hour. If something like this happens, they should be able to click the home menu and reset their server, right?
