Server shuts down abruptly when installing hotfixes in Docker

This resolution describes hardware recommendations that should only be implemented at the discretion of your team. Liferay Support is not required to make any hardware recommendations or offer any guidance on hardware selection, installation or configuration.

Issue

When attempting to install a hotfix using Docker, the server appears to start normally but then shuts down abruptly. However when the hotfix is removed, everything starts up normally.

Environment

• DXP 7.3
• DXP 7.4

Resolution

This issue is likely due to insufficient memory, which can be resolved by either increasing the memory on the Liferay container or Docker itself:

1. Increase the memory to the Liferay container by increasing the value after the -m flag:

   docker run -it -m 8g -p 8080:8080 liferay/portal:7.4.3.29-ga29

2. Check how much memory is allocated to the docker engine by navigating to Preferences > Resources > Advanced and increase the memory if it's less than 8GB.

Additional Information

• For MAC users, 8GB should be enough, but others reported that 12GB was needed.
