When I kill a running job in Jenkins at the very early stage of its build, it doesn't get killed and goes to a null state. I can't see that in the main console, but when I go to the job page, I see the job running. I am unable to kick off another build for the same job as it says that the job is already running. Please see the screenshot.
The only way I have for now is to restart jenkins. It has been happening quite frequently in the past 2-3 days time. Please send me a resolution for this at the earliest, it is not easy to restart jenkins very often in a busy day.

Thanks,
Aswini
