Yeah, I'm just chilling to be honest, obviously not doing much.

 

@Commander_HK47 if your log file is becoming large have you inspected it to see if there are extra lines / unusual lines in the log you wouldnt normally see... I can try replicate this if you provide me more info on what you do while your on ecc :)

 

@bobman3355 @NessXXIII @destroyer2441

May have figured out a few things towards the issue. I need a few details to help this so please post a few requested details here, or pm them to me.

1. Launcher type (vanilla, fabric, forge, etc):
2. Versions recently played on:
3. List of ALL mods whether used on ECC services or not:
4. Recent activities on ECC when this happens:

Thanks

EDIT: 1 issue found so far that has a fix for users with CommandMacros possibly resulting in large .log files.

 

@FwgKing

I no longer get massive files. On average mine are about 25 MB and I am guessing from mob farming with command macros. Here are the answers.

1) fabric
2) 1.16.5
3) command macros, fabric api, optifabric, mod menu
4) not sure but assuming mod farming.

 

So there have actually been a few issues I've discovered that result in stupidly large log files. Still waiting on a few more inputs to investigate further into, but as for now, here's the simplest one to fix and it's with CommandMacros.

DO NOT make a macro and not implement a macro button with it/to toggle it, or you will be spammed 60 times a second like --->

Still waiting on more replies to make sure I've zoned on the other issues, but definitely working on it.

 

Update on the latest findings.

Still could be many things that create large files, but here's one of them that does a few k mb a minute.

So to start things off, when switching servers using a completely vanilla client on 1.16.5, I get this message -->

After extensive testing through every available version, and with various client loaders, the problem seems to arise from 1.16 and up. This is the only group of versions that receive any error message currently for myself.

Weird problem arises when I have someone else test the problem being "Users Connecting to SkyBlock on 1.16 and up get error spammed", with the exact same replication steps on a completely vanilla client, and their set of errors is nothing like mine being -->

At the very least through my few days of testing and log-diving, there is an issue with errors being spammed in logs while on SB using a version of 1.16 and up.

 

@FwgKing Awesome job looking into this and reproducing it. Based on the stacktrace:

You said this is being logged hundreds of times per second - that would definitely be the reason behind the massive logs.

I was able to track down some bug tickets open about this on Mojang's Jira board:
https://bugs.mojang.com/browse/MC-198460
https://bugs.mojang.com/browse/MC-189565

The gist of this is:

• Mob spawner rendering is buggy for: bees, enderman, polar bears, wolves, piglins, evoker fangs.
  • The image rendering fails, and logs a message each and every time. This rendering happens at the rate of your framerate. Hence, many logs per second.
• This will be supposedly fixed in the 1.17 release.
• We are SOL until 1.17.

This does not appear to be ECC specific, and appears to be a bug with 1.16 Minecraft versions in general.
