With the new snapshot I am getting a lot of spam on the console.

This might comes from entities created in older versions. Does it happen every time you open your world?
migrated
It's ongoing, it's possible it only happens when a chunk is first loaded with the new version, however this world was created fresh for 15w38a, so it is a moderately new world.
migrated
This seems to be an issue with entity handling when chunks are unloaded. I've been flying around my server in spectator mode with the console open to keep an eye on it, when I travel away from a Nether Portal PigZombies are in the console, it doesn't happen when I load the Nether Portal.

confirmed here, unable to follow the console messages since the 36d version
not confirmed :
" it's possible it only happens when a chunk is first loaded"
it happend everytime, chunk loaded, unloaded, start stop the server, i suspect a problem with dimensions ( since the method travelToDimension(player, int) changed to travelToDimension(player, int, position) )
see https://bugs.mojang.com/browse/MC-89210 i just opened
ps, i saw this error spam in fresh version AND in my modded version
migrated
I can also confirm this.
Version: 15w39b

Just to add to this, I was watching the logs and saw MineCartChests so I tp'd to one and its throwing it's items on the floor, got 1 1/2 stacks of diamonds from it so it seems like it throws it out a lot.

Can confirm these errors on linux server. Seems to come up when new snapshot is used and entities in already loaded chucks. Not sure if this is the cause though. I can support
migrated
Confirmed on Windows 8.1 running dedicated server 15w39c.

These log messages are "just" warnings that a potential problem with duplicate UUIDs was detected and prevented. It's not a problem, the code I wrote to fix the associated bug should work. I just left the messages in for now, so that I can see how often my code actually prevents it from happening, this will be changed eventually.
TL;DR: it's not a bug, just some useful debug logging
migrated
Searge, does that mean the MinecartChests throwing out items onto the ground is unrelated?
migrated
Yeah, I have just noticed the minecart chests spewing their items, I figured it was related to this, since I see a lot of duplicate UUIDs for the minecarts as well as other entities.
migrated
i found the solution
pointcut spam() : (execution( * org.apache.logging.log4j.spi.AbstractLogger.warn(String,..)));
Object around() : spam() { if(((String)thisJoinPoint.getArgs()[0]).contains("pending"))return null;return proceed();}
150 to 250 spams by minute removed
now i can read my logs 🙂

Created a new issue for the Minecart chest item dupe/spewing MC-89602

Thank you "me"
But how and where put your code in place ?
Is it easy ?
thanks !
