Python script gets killed

Posted on September 21, 2016
Python Ubuntu
Asked by tolgaozden77

I am a newbie to digitalocean.

I have just created the smallest VPS and then install python, pip and all required python modules in order to move my scripts which work fine on local server.

Right now, my script starts without any problem but suddenly gets killed. How can I understand the reason and solve this problem?

Do you have any idea under which circumstances digitalocean VPS kills any running script?

If this is smallest Droplet it could that script run out of memory. You should check syslog for Out Of Memory killer. syslog is located at /var/log/syslog and you can opet it with your favourite text editor:

nano /var/log/syslog

Here you can try to find Out of Memory (OOM) killer signal. If there are for your script, it means you ran out of memory. If you need help with logs, post part of it here, but make sure you redact sensitive informations if they are any.

Heya,

In such cases where you have the smallest Droplets, it’s possible the issue is happening because you don’t have enough memory. That could be checked in the /var/log/syslog log. If that is the case, you’ll OOM signals which are Out of Memory messages.

In such cashes people would go for the upgrade right away, having said that, before that you can try using SWAP. Swap is a portion of hard drive storage that has been set aside for the operating system to temporarily store data that it can no longer hold in RAM. This lets you increase the amount of information that your server can keep in its working memory, with some caveats. The swap space on the hard drive will be used mainly when there is no longer sufficient space in RAM to hold in-use application data.

The information written to disk will be significantly slower than information kept in RAM, but the operating system will prefer to keep running application data in memory and use swap for the older data. Overall, having swap space as a fallback for when your system’s RAM is depleted can be a good safety net against out-of-memory exceptions on systems with non-SSD storage available
