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.
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. Finally, the document will describe the situation, the problem, the analysis, and the result.

8 +No data is delivered to a Mendix application.

9 -== 2. Exit code values ==
10 +== 2. Problem ==
10 10  
11 -* Exited with code *0*: The application inside the container completed its work successfully without any errors.
12 +The problem in this case was expected to be related to the old build numbers of the model.
12 12  
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.
14 +== 3. Analysis ==
14 14  
15 -* Exited with code 125: The docker run command was not executed successfully
16 +=== 3.1 Reproduction ===
16 16  
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.
18 +N/A
18 18  
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.
20 +=== 3.2 Analysis ===
20 20  
21 -* Exited with code 137: The container was forcefully stopped. This happens when the container exceeds its memory resource limit (OOM)
22 +The problem led us to investigate the health of the JMS and the eMagiz Mendix connector. The JMS was restarted due to the amount of 'client connection failed' warnings that were received. Due to the problem being a Mendix application which was not receiving data, the eMagiz Mendix connector was also restarted. Afterwards, everything worked fine again.
22 22  
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.
24 -* Exited with code 255: Container exited, returning an exit code outside the acceptable range, meaning the cause of the error is not known
24 +== 4. Result ==
25 25  
26 +The old build numbers used in the model are expected to have an influence on the performance of the eMagiz Mendix connector. We recommend to upgrade these build numbers or to migrate to the current-generation runtime.
