Why is process not being displayed by TOP
- by drN
I am running a Mathematica script (this question probably doesn't fit in Mathematica.SE however) and I know that it generally takes up a lot of RAM and loads up my cores. However, althought pgrep MathKernel is showing a pid, I find that top doesn't show this in the top processes, although I notice that it is taking up about 2.25GB of the 8GB available to me.
pmap -x my_process_id

ps aux shows that the process is taking about 12% (In asterisks)

Did this process fail and is the MathKernel just lingering?
