Crash upon loading chunks when teleporting

Resolved
Fixed
17

I am unable to track down exactly what the cause of the crashes are but sometimes when a player is teleported to some location, the server stalls for a very long time and eventually crashes or has to be manually closed and restarted.

The Minecart Improvements and Winter Drop experiments were both enabled.

I have attached the crash report which we got on a vanilla dedicated server in 24w40a.

The code section that caused the crash was refactored a bit in 24w39a which is likely the cause.

This was on a very old server so could be any number of things such as maps, large amounts of items, large amounts of data in items/blocks, etc.

This was the error in the log when running the vanilla server:

And this is the error we get from the same kind of crash but when running a Fabric server:

As you cannot tell what server this was, I am removing the private marking from this report.

@unknown I can tell you what the server is, I just did not think it was relevant. I would very much appreciate you re-adding the private marking (and I can tell you the name of the server if you need it), otherwise I would like to remove the attached reports.

Does the game freeze up before the crash, I had opened a bug report in which Teleporting was a part of the process which makes me wonder if in fact the issue could have been related.

@unknown: Grey meant that since we don't know what server it was, this report doesn't need to be private.

Yes. There is no need for the report to be private as the server is not stated anywhere. The report being private means the community cannot contribute to the bug report, which we ideally would like for every bug report as this is a community bug tracker.

The attached reports show no private information.

Resolved as AR as per Uriah's comment.

Are you able to reproduce this still on pre5? The crash report should contain more details about what went wrong. 🙂

I will update the server as soon as possible and stay vanilla and let you know as soon as we get another crash 🙂

I've uploaded crash-2024-10-16_15.26.28-server.txt which happened in 1.21.2 Pre-Release 5 🙂

Is the datapack https://github.com/DorkOrc/PandamiumDatapack/tree/master/snapshot_pandamium_datapack ?
