Anticrash plugin for Minecraft server?

I'm looking for a plugin for my Minecraft server that minimizes crashes. Unfortunately I'm currently crashed very often.

Doesn't exist and is impossible.

You would have to fix the bugs, but that is in the hands of the developers of Minecraft and plugins / mods.

I know the thing pretty well,

Install ProtocolLib first:

https://dev.bukkit.org/...llib/files

(Pay attention to the correct version of Minecraft)

Then install a CustomPayloadFixer:

https://www.spigotmc.org/...got.39891/

(Kicks everyone who wants to crash the server)

Then install Anti Jigsaw:

https://www.spigotmc.org/...ver.47972/

(Fixes almost all crash bugs)

Unfortunately, there are a lot of crash hacks nowadays that are very difficult to fix.

The best AntiCrash plugins unfortunately cost money, e.g. CasualProtector

I don't know if you have any idea of it, but today the server owners have to take it into their own hands.
Minecraft developers don't fix that.

Infinite number of servers such as GommeHD, Hypixel etc. Took it into their own hands and it worked.

I have a clue about software development and it is impossible to develop a plugin that generally prevents errors.

You could fix any bugs you find, but that will probably require your own or customized server implementation at some point, because the plugin API doesn't allow that much.
And then it is statistically impossible to find and fix all errors, so you need a program that restarts the server as soon as it crashes.

So no, there's no "anti-crash plugin", you could only fix known bugs, but that only works as long as no new bugs occur, then the work starts again.

And Mojang takes care of the mistakes in her program. If any server implementation or plugin / mod has a bug, then of course that is not their job.

Oh, there's no plugin that prevents this?
Here are a few links:

Otherwise:

There are many more

The plugins only fix the known bugs.

As I said: it is impossible, there's no "anti-crash plugin", there are only fixes for known bugs and nothing more.

If there are further errors, none of this helps, the server still crashes.

Maybe you can build a kind of "observer" around it that logs players back in if they fly out, but that would only cause the symptoms and not the mistakes.
And it still doesn't help against a crash.

There are concepts of how a server application can catch up on its own, I have already developed something myself, but something like this can't be tinkered with in the form of a plugin, the server application must be able to do this on its own.
