CPU usage seconds increasing and nothing running

Hi, I have nothing running on my account, and I can see the CPU usage seconds keep increasing randomly. Can you please point me what's going on? Thank you in advance

Sorry about that! You do actually have some processes running, but due to a bug they weren't showing up on the process list. I've deployed a patch, so if you go to the "Consoles" tab, and click on the "Fetch process list" button, you'll see them now.

They're related to a Jupyter notebook session that you must have been running earlier -- Jupyter notebooks, even when inactive, will "sip" CPU time at a rate of 1 second per minute or thereabouts. You can stop that by simply killing processes with "jupyter" or "sudospawner" in their name.

Thanks very much giles!

No problem!
