Docker container with --restart=always not restarting after Out of Memory error

As you can see bellow my restart police is set to "always", but almost every night I get an out of memory (expected and not the issue I'm trying to solve here) and in the morning the container is stopped. If we check the RestartCount property it says 2, does this mean that it restarted twice and then stopped? Is it possible that it failed during the start process for some reason and stopped trying? Everything works fine when I start it again manually.

Here is the docker inspect result, let me know if you have a clue on what's happening.
