I think it is more server limit. But can you try latest version and see if you get same problem?

I tried latest version and nothing changed. I also tried to find any solution but there was no mention of server restrictions anywhere.

can you post latest stack trace or is it same also? I can tell you not always is the limits described at all, so you have to work blindfolded some times.

Uts fully the same.

And I found interesting bug: when i remove some recipes to reduce packets amounts, they on the contrary increase:
PacketPlayOutRecipeUpdate is 2245575 (default)
PacketPlayOutRecipeUpdate is 6943290 (after removing recipes)

If I restart my server again, the amount of packets return to the first value

Alright, yeah I think the increase is because you not remove from client. Could you send your recipe.yml and item.yml? I guess you have a lot of metadata on the items.

Alright, you seem to have a huge amount of items with extensive lore, and you've also set up over 200 recipes. My assumption is that you have 'learn recipe' set to true also?

It's possible that the server is struggling to send such large packets and ends up kicking the client. Unfortunately, it seems I can't directly resolve this issue beyond limiting the number of recipes you can create. I consulted some experts about this problem, and it turns out you can't add an unlimited number of recipes due to packet size limitations.

The situation might improve in upcoming Minecraft updates, possibly after 1.20.1 or 1.21, as they might allow for larger packets. However, there will still be a limit.

At this point, one possible solution could be trying to turn off the 'learn recipe' feature. Keep in mind that the knowledge book might not function properly anyway when you're using custom data on your items. This might add a bit more work for your players, but once they've done it once, the right ingredients will be saved. However, please note that the recipe will be removed when a player rejoins the server.

The feature "learn recipe" was never enabled, but it didn't help. I started crafting anew, but another problem arose: half of the recipes works properly, while the others does not (no result in my workbench). At the same time, I don't see any error in the console

Alright I can't do so much about the error.

Have you update to latest? This one 2.5.9.1.5?

Don't know if this should still be open issue, as is no practical way to solve this.

Only way is just making own crafting system that doesn't send recipes as a package to the user.
