Issue Running Jupyter Notebook Server on ARM Debian 8.6: <IDS|MSG> Not In List

[tom-saildrone]

Hi,

I'm trying to run a Jupyter Notebook Server on an ARM machine running Debian 8.6 Jessie. I can get the kernel to start, but after making any changes in a notebook, the kernel crashes with the following error:

[I 21:46:08.426 NotebookApp] Kernel started: ac714d21-4281-4272-a6e2-48d8a68763c2

Obviously, this seems to be an issue with Tornado and/or zmq. I've tried using older versions of ZMQ/Tornado, as this seems to solve similar issues posted here and on StackOverflow, but it hasn't helped so far. I've tried numerous configuration options, but am out of ideas at this point. I've tried this on other machines running Debian 8.6, and other ARM machines, but I have a feeling there is a specific scenario occurring with this machine that is causing this. Any ideas/help would be greatly appreciated, unfortunately updating the kernel/OS isn't an option at the moment. If there is any other info I can provide, just let me know.
