In this document, we will use the information from the actual root cause analysis to make a generic view that can be used if you run into the same or a similar problem in the future. The focus will be on providing insights into what is an exit code, the main exit codes returned by a container when it stops and how can that help you to resolve your problem.

In a previous [[microlearning>>doc:Main.eMagiz Academy.Microlearnings.Crash Course.Crash Course Platform.Runtime Overview||target="blank"]] we explained that a container can have multiple statuses. Among these, there is the status Exit which is returned by the container uppon stopping and comes together with a code. The exit code usually points out the reason why the container stopped. In the section below we describe the most common exit codes that you can encounter in eMagiz.

== 2. Exit code values ==

13

14

* Exited with code **0**

15

** The application inside the container completed its work successfully without any errors.

16

17

* Exited with code **1**

18

** There was a general error in the application, which could be due to a variety of reasons like incorrect arguments or a failed dependency.

19

** For example when you are missing a property value.

20

21

* Exited with code **125**

22

** The docker run command was not executed successfully.

23

** This usually occurs when eMagiz fails to execute a certain command on that container, e.g. Start, Stop.

24

25

* Exited with code **126**

26

** The command inside the container was found but cannot be executed. This can be due to permission issues or if the command is not executable.

27

** For example, when eMagiz is running on premises and the permissions are incorrectly configured.

28

29

* Exited with code **127**

30

** The command was not found. This usually happens if a script is missing or the path is not set correctly.

31

32

* Exited with code **137**

33

** The container was forcefully stopped

34

** This happens when the container exceeds its memory resource limit (OOM).

35

36

* Exited with code **139**

37

** The application inside the container crashed due to a segmentation fault, which is usually caused by accessing memory that the process does not have permission to access.

38

39

* Exited with code **143**

40

** The container stopped gracefully after receiving the operating system's SIGTERM signal, which instructs the container to do so.

41

** For example, when you command the container to stop via Deploy Architecture or when eMagiz stops the container, e.g. Stop Machine deployment step.

42

43

* Exited with code **255**

44

** Container exited, returning an exit code outside the acceptable range, meaning the cause of the error is not known.
