When scoreboard.dat file is over 2.2 mb, server becomes unjoinable.

When a server has a scoreboard file with total size over about 2.2 mb, no one can join the server without getting kicked with the message in the attached screenshot.

This has been tested multiple times, and shown to be the scoreboard file. When the file is swapped for a different one, the server becomes joinable.

To reproduce:

  • Get a server

  • Put enough entries in the scoreboard file that it goes over 2.2 mb (such as putting a large quantity of mobs on a team)

  • Relog

Note:
A rather common cause of this is MC-92266.

How many mobs do I need to put on a team to get a 2.2mb scoreboard file?

On the server where I discovered this, due to the large number of stored players, it took about 30000. For you, probably upwards of 60000.

Maybe /scoreboard every single type of entity to join a scoreboard using repeat command blocks and summon a lot of experience bottles?

is this still in 16w03a?

I haven't checked recently.

On my world, I have generated a function that enters over 100k fakeplayers into a single scoreboard, which puts the scoreboard.dat at 2.65mb. Upon entering the world, everything seems fine.

This is still an issue in 1.15 and this also affected /data storage as well.

I've reopened this and marked it as affecting 1.15

Does this still affect 1.18.2?

I am having the same issue. For some reason my scoreboard.dat file keeps getting huge. Ill check it and it will have over a million player entries
