EC2 instance kills the long running process, ssh connection closed

Question

I'm running a python script which processes large amount of data and takes around 16 hrs to complete. The cpu usage is shown below in the pic. The gap between the two peaks is where, ec2-instance kills the running python script and logs out any ssh connection. The ram memory utilization is also shown below. Any pointers where to look for the problem?

Answer

It is most likely that ssh is timeout, I recommend the following options to launch your scripts in the background

* You can add your script to **cron** 
to be run regularly.
* You can run your script manually, and detach+background it using **nohup**.

I hope it can help you, if not, could you add the command you use to run the python script?
