@cviguier Thanks for reporting this and sorry about the issue here. I see that you can't provide the notebook, which I understand, but it might make it a bit harder to track down. I'll try to dig in on this myself creating a similar large notebook with plotnine plots today to see if I can repro. Does look like it might be a memory issue though, I agree.
If you do happen to run into this again, if you right click on the console tab in the developer tools you can save the entire console log as a file. If you do that you can just drag that full file into a message box comment here on github. Might help me to see the entire log.
@IanMatthewHuff THank you very much for the quick answer. Once it starts, the error is quite consistent. Please find the log attached. I hope it helps. Thank you again for your help.
I've been playing around with a big file with plotnine charts (10,000 elements, 40MB file size) and I'm currently unable to repro it, but I'm still trying. In those extension host warnings that you see before the crash while typing in the markdown. It looks like it's creating a cpuprofile file on your system. Could you attach one of those as well? Might let me see what it's churning on when editing in the markdown.
Also just to make sure, you are editing the markdown without even running the file after the re-open, right?
Thank you for your effort. I will try to reproduce a notebook with the bug that can send you. Please find attached the cpuprofile it generates. Yes, I go straight to a markdown cell and I edit it.
@cviguier If possible could you try downloading our newest development build and giving the same scenario a try? https://github.com/microsoft/vscode-python/blob/master/CONTRIBUTING.md#development-build Looking at the scenario I believe that our saving code might be a problem (as you type the notebook it is saving behind the scenes). Our new code has been refactored to save less often, so I believe that it would handle this scenario better.
@IanMatthewHuff Thank you for the suggestion. After short experiments, it looks like it doesn't crash. I'll continue working on the document and see if I meet any problem. If Can finish my work without any trouble, I will close this issue.
I noticed some error messages, but I believe they are not related (but at rather related to Jedi, I messed with it as I saw it might have been a cause of my original problem). I'll attach the log if you want to have a look.
Thank you for your help.
Thank you very much for your help. It seems that using the dev version has stabilised the notebook.
Awesome and thanks for reporting this as well. While looking into this issue for you I think that I also noticed a related performance issue with notebook saving, should be able to clean that up as well and I wouldn't have noticed this without your report.
You're welcome. I try my best to not open issues for nothing, but I was really struggling to find a solution to this problem. I'm happy this helped, because you helped me a lot. Cheers.

Thank you in advance for your help.
