Having the same crash issue as i had when flying last time i had a modded server

Server Discussion

So I’m having the same issue as last time when i had a modded server using sponge forge with mods and plugins. Basically when I /fly at speed 10 and just keep flying around really fast, after a while the server crashes. I even set a world border and pre-generated the world but it still happens. I’m current only using 4gb or ram on centos 7 and just 3gb allocated to the minecraft server but last time i had 16gb and 10gb to the server. I don’t get it. Also no crash report got generated.

Could you post the server logs?

Here is what happened before it crashed, I just replicated it again by flying at speed 10 though doesn’t seem to say much.

It also generated a hs_err_pid

Here is what that says:
had to upload it since its too big for pastebin:

This means Java ran out of memory. You’ll need to increase the amount of memory you allocate to Minecraft.

This error also might mean that while you are allocating the Minecraft server enough RAM, you are allocating it more than the actual system/OS can give, so it crashes.

actually this time is sorta came up with an error:

I would get more ram but i don’t think it will fix the problem because last time i had a modded server i had 16gb of ram and allocated 10gb to the minecraft server the rest for the other system resources.

That error is actually a client’s fault. It connected to the server and then shut down without properly disconnecting. You can’t really do anything about it.
