Hi,
I have a 2GB memory and 40GB Disk DO. I am running a python script on this and it gets killed at a particular line (I know where as it is a bit of a memory-intensive line of code). This script runs on my personal mac without a problem.
What is happening? Can I set the memory allowance of python in linux manually? I remember hearing about OOM. How can I go about this? Is this a good solution at all?
Thanks a lot.
You can check in the kernel logs if you're OOMing (check /var/log/kern.log or others) and the solution is to add additional memory by upgrading the droplet.
If you see messages like:
[1711385.762978] Out of memory: Kill process 21405 (apache2) score 47 or sacrifice child
[1711385.763420] Killed process 21405 (apache2) total-vm:296064kB, anon-rss:23560kB, file-rss:0kB
(but with python instead of apache), then your processes are indeed being killed because of OOMing.
If this is a one-time thing and you don't expect to regularly use this much RAM, consider temporarily using a swap file.
Thanks for your help, gp. What is a swap file? Is it this:

Yes, I see the kill:
[1236561.813065] Out of memory: Kill process 12689 (python) score 900 or sacrifice child
[1236561.813119] Killed process 12689 (python) total-vm:2218116kB, anon-rss:1899840kB, file-rss:4kB
Can I increase or decrease the score?
