When i run cellranger count, the process become dead. The process become defunct after I kill cr_lib and mrjob.

And I could not access to working directory of cellranger. But I could access to other directories.

When I used top to check the systeming status. The cpu loading is very high, but there is no tasks running currently, just found the three zombies.

I have tried kill all the process and parent process with sudo, it is still not working.

How to kill the three zombie process or how to make the computer running as normal without rebooting
