Hi Soheil
The last message in the screen shot you posted is pretty clear. The OS killed the job due to too many hardware resources being used. There could be some Linux Cgroup rule (control group) that limits the amount of RAM that can be used on the system, like say 90%, then kills the process taking the most RAM if that rule is broken.
You should show this to the system administrator - it would not be unusual for a Cgroup rule to be accidentally set on one, or more, computer node (mistakes happen). Or maybe they mean for the rule to be there and you need to work within its defined limit.
