Python script is stopped due to "Terminated" in linux

Question

I need to run python script 24/7 in screen. But my script got "terminated" and stopped.

I don't know why my script is stopped and show only "Terminated" message without getting any error message.

Therefore I run strace -p 253141 in another screen. I got the below message when the python script receive "Terminated".

pselect6(0, NULL, NULL, NULL, {tv_sec=0, tv_nsec=0}, NULL) = 0 (Timeout)
pselect6(0, NULL, NULL, NULL, {tv_sec=0, tv_nsec=0}, NULL) = 0 (Timeout)
pselect6(-514, NULL, NULL, NULL, {tv_sec=0, tv_nsec=15232515}, NULL <unfinished ...>
--- SIGTERM {si_signo=SIGTERM, si_code=SI_USER, si_pid=253891, si_uid=1000} ---
<... pselect6 resumed> <unfinished ...>) = ?
+++ killed by SIGTERM +++

May I know why my python script stopped?

How can I troubleshoot the root cause?

How can I solve this issue?

Answer 1

The process is being killed by the OOM killer (Out Of Memory Killer), which is a process of the operating system whose job it is to kill jobs that are taking up too much memory before they crash your machine.

Try tweaking your code, as-is it is taking up too much processing power, and thus on the verge of crashing your machine.

This answer is for the Unix OS, but because they are so similar, maybe it will work:
