It might be that the kernels are not properly beeing shut down upon refresh / closing of browser tabs. We might need to implement an automatic shutdown in case of inactivity in jupyter_server. |

Yeah, I am thinking about making a hack cron job with |

@scottlittle you can use the traitlets configuration system to specify how often kernels are culled, so they can be terminated when they are not active anymore. For example: voila --MappingKernelManager.cull_interval=10 --MappingKernelManager.cull_idle_timeout=10 example.ipynbOr create c.MappingKernelManager.cull_interval = 10
c.MappingKernelManager.cull_idle_timeout = 10Related to #55. |

Which version of voila were you using? After 0.10, this may happen less often since the browser now triggers the shutdown of kernels (till 0.10 there was an issue with that for chrome). And otherwise what @jtpio says seems the best option. |

@scottlittle by that I meant starting the notebook server with This should pick up the cull settings. |

@jtpio got it. After opening, running, and closing some apps and letting them be culled, this is what I got (see Jupyter processes at bottom): I didn't shutdown the voila before doing this, and you can see that the problem persists there. |

I'm running into memory issues while running voila. It seems like old processes hang around and slowly increase the memory until almost complete unresponsiveness and I need to reboot. I am using a fresh install of Ubuntu 18.04 on AWS, pip3 install everything, and redirect port 8866 to 80 using iptables. Here's a screenshot of
htop:I'm unable to sort by anything at this point due to unresponsiveness. I was wondering if anyone has experienced anything similar and what they have done about it.
TLDR; After launching voila, I have a bunch of zombie processes eating my memory until I have to reboot.
