Cannot kill a process

New to AiiDA

Hi,

I cannot kill the process 836. I do not remember where it comes from, and I do not need the calculation anymore.

But after I stop daemon, repair and restart daemon, I still cannot kill the process 836. What is the problem…

Many thanks for that.

There might be some delay between starting the daemon again and it picking up the job, so you can kill it. Did you try verdi process kill again after waiting a bit for the daemon to fully start up. 30 seconds should be enough.

If that doesn’t work, does verdi process play work, or do you get the same unreachable error?

If you don’t care anymore about the job, you can simply delete it as well with verdi node delete 836.

I think it is the first situation. I did not do anything else. And the job disappeared now.
