Plugin Version: dynmap v3.1-457
Server Version: Paper version git-Paper-553 (MC: 1.16.5)

sometimes the server does not shut down completely and ends here:

i am not sure if it is really the same problem

Linking that thread as it has more information

the problem still exists (Paper Build - 1.20.1 and dynmap v3.6-899)

Could this possibly be opened again?

I'm not sure if it's because of dynmap or the hoster/docker. My hoster uses docker containers for the Minecraft server. And sometimes it just happens that the container closes before the server is completely shut down. And this happens at exactly this point.

each plugin is only given 10 seconds to shutdown, if it takes longer, it just gets killed, especially apparent with sqlite as it is not fast, we recommend moving to mysql as that is really hard to corrupt, which is not the case with sqlite

So it never takes 10s for me. Even if it takes 1-3s (for dynmap), the problem described happens.

Can you open the issue again or should I create a new one?
