User Processes not releasing Memory #507

Open elijahomolo opened 5 years ago

elijahomolo commented 5 years ago

Hi,

I have been seeing these processes called "ZMQbg/1" over and over that do not have any CPU activity. I'm trying to get an understanding of what these processes are and how can they be managed besides killing them.

I have seen these processes on multiple Notebook users. Some users jobs error out due to out of RAM. From the information I've found, these look like ZMQ processes. I believe Jupyter uses ZMQ pipes to communicate in the background hence the processes.

Can anyone confirm/validate this and if so, what's the recommended way to manage them?
