kernel can only autorestart once
Name: jupyter-client
Version: 7.0.2

kill kernel process first time, it will autorestart . kill it agian , nothing will happen

seems self.shutting_down in KernelManager never set to False ,after restart

Hmm - I'm not experiencing this. If I kill the kernel pid, the auto-restart takes place each time (across all 3 attempts). That said, I see what you mean regarding self.shutting_down and it seems it deserves a reset in the post start method. Did you want to take a crack at this? Since I'm not reproducing this, it would be good for you to at least check out the solution (from wherever that comes).

this issue occurred when jupyter-client==7.0.2, and i add "self.shutting_down = False" in funciton "async def _async_post_start_kernel(self, **kw) -> None:" it will be ok

Hi @mofanke - thanks for the update.

Yes, that sounds like the correct approach. Did you want to go about creating a pull request for this?
