2		-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.
	2	+In this microlearning, we will give insights into what is an exit code, the main exit codes returned by a container when it stops and how can that help a Support Engineer to conduct an RCA.

8		-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.

14		-* Exited with code **0**
15		-** The application inside the container completed its work successfully without any errors.
	11	+* Exited with code **0**: The application inside the container completed its work successfully without any errors.
16	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.
	13	+* Exited with code **1**: There was a general error in the application, which could be due to a variety of reasons like incorrect arguments or a failed dependency.

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.
	15	+* Exited with code **125**: The docker run command was not executed successfully
24	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.
	17	+* Exited with code **126**: 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.
28	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.
	19	+* Exited with code **127**: The command was not found. This usually happens if a script is missing or the path is not set correctly.
31	31
32		-* Exited with code **137**
33		-** The container was forcefully stopped
34		-** This happens when the container exceeds its memory resource limit (OOM).
	21	+* Exited with code **137**: The container was forcefully stopped. This happens when the container exceeds its memory resource limit (OOM)
35	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.
	23	+* Exited with code **139**: 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	38
39		-* Exited with code **143**
40		-** The container stopped gracefully terminated 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.
