12.1 | 8 | In a previous [[microlearning>>https://docs.emagiz.com/bin/view/Main/eMagiz%20Academy/Microlearnings/Crash%20Course/Crash%20Course%20Platform/Runtime%20Overview||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 go into more details for the most common exit codes that you could see in eMagiz. |

| |
13.1 | 17 | * Exited with code **1** |
| |

| |
1.1 | 24 | |
| |
13.1 | 25 | * Exited with code **126** |
| |
14.1 | 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. | ||
| |
1.1 | 28 | |
| |
13.1 | 29 | * Exited with code **127** |
| |
14.1 | 30 | ** The command was not found. This usually happens if a script is missing or the path is not set correctly. |

| |
13.1 | 32 | * Exited with code **137** |
| |
14.1 | 33 | ** The container was forcefully stopped |
| 34 | ** This happens when the container exceeds its memory resource limit (OOM). | ||
| |
1.1 | 35 | |
| |
13.1 | 36 | * Exited with code **139** |
| |
14.1 | 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. |
| |
9.1 | 38 | |
| |
13.1 | 39 | * Exited with code **143** |
| |
14.1 | 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. | ||
| |
12.1 | 42 | |
| |
13.1 | 43 | * Exited with code **255** |
