[Crash]: Frequent server crashes due to "Ticking entity" issue #1551

What happened?

Advance note: I installed other mods, two about adding more planes and a drop cleanup mod, which I don't think will have an impact on the AI convenience.

My server has been up for four days now, and since yesterday, the server has started crashing frequently because of this error, and looking at the logs I think it's a problem with the monster AI, but I can't pinpoint the exact reason why. It even crashed four times in a row in the early hours of this morning

This is the log error: net.minecraft.ReportedException: Ticking entity at net.minecraft.server.MinecraftServer.m5703(MinecraftServer.java:897) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.server.dedicated.DedicatedServer.m5703(DedicatedServer.java:283) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.server.MinecraftServer.m5705(MinecraftServer.java:814) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.server.MinecraftServer.m130011(MinecraftServer.java:661) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.server.MinecraftServer.m206580(MinecraftServer.java:251) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at java.lang.Thread.run(Thread.java:840) ~[?:?] Caused by: java.util.ConcurrentModificationException at java.util.LinkedHashMap$LinkedHashIterator.nextNode(LinkedHashMap.java:756) ~[?:?] at java.util.LinkedHashMap$LinkedKeyIterator.next(LinkedHashMap.java:778) ~[?:?] at net.minecraft.world.entity.ai.goal.GoalSelector.m186081(GoalSelector.java:118) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.world.entity.Mob.m6140(Mob.java:753) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.world.entity.LivingEntity.m8107(LivingEntity.java:2548) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.world.entity.Mob.m8107(Mob.java:536) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.world.entity.monster.Monster.m8107(Monster.java:42) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.world.entity.monster.AbstractSkeleton.m8107(AbstractSkeleton.java:116) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.world.entity.LivingEntity.m8119(LivingEntity.java:2298) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.world.entity.Mob.m8119(Mob.java:337) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.server.level.ServerLevel.observable$track(ServerLevel.java:7169) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.server.level.ServerLevel.redirect$bib000$observable$onTickNonPassenger(ServerLevel.java:7185) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.server.level.ServerLevel.m8647(ServerLevel.java:693) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.world.level.Level.m46653(Level.java:479) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.server.level.ServerLevel.m184063(ServerLevel.java:343) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.world.level.entity.EntityTickList.m156910(EntityTickList.java:54) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.server.level.ServerLevel.m8793(ServerLevel.java:323) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] at net.minecraft.server.MinecraftServer.m5703(MinecraftServer.java:893) ~[server-1.20.1-20230612.114412-srg.jar%23911!/:?] ... 5 more

The following four error reports are basically very similar, all because of a single error and then the server immediately crashed: crash-2024-03-29_01.19.07-server.txt crash-2024-03-29_01.26.25-server.txt crash-2024-03-29_07.19.29-server.txt crash-2024-03-29_07.44.13-server.txt log--2024-03-29_01.19.07.log log-2024-03-29_01.26.25-server.log log-2024-03-29_07.19.29-server.log log-2024-03-29_07.44.13-server.log

Were you or any players on your server fighting a Wither Skeleton when the server crashed?

KNaiFen commented 5 months ago

Oh actually about an hour after sending out this ISSUE I found the cause and banned the generation of the Wither Skeleton and have never crashed due to this issue again. As far as I can verify there was no one in the server fighting the Wither Skeleton at the time of the crash, it just got refreshed and stood there and the server had a probability of crashing. I've encountered a lot of Wither Skeleton in my playthroughs, but there were no crashes then, so I'm guessing that this monster causing the server to crash is a probabilistic event.

Same issue here on 0.2.56

Keeps crashing on logging in, had to move my character with NBT editor to 0,128,0 in order to fix it. I was on a pirate ship with a lot of skeletons. As you see below exact same error as OP.

As far as I remember they all where normal skeletons.

The following assumes you were fighting a Skeleton or Wither Skeleton when the server crashed. Can you please locate the player data file corresponding to your player data on your server, then zip and attach it in a new comment? If that is not possible, can you please run /recipe take @s * followed by /data get entity @s, then post the resulting output? If that is not possible, can you please take screenshots of all your armor, weapons, and Curios then attach them?

Possemaster commented 4 months ago

Hey @James103 I have found the issue for me was the Thorn Pendant Necklace from Artifacts that cause the issue. I removed that pendant and could slay 100s of skeletons in the dungeon without issues. Went in naked with only the pendant and after 4-5 hits from the skeleton the server crashed. So 100% the pendant cause the issue.

ID: artifacts:thorn_pendant

James103 commented 4 months ago

Do you get a similar crash if you enchant your armor with Thorns then let (Wither) Skeletons attack you and die from that Thorns effect?

x13x54 commented 2 months ago

Caused by thorns killing skeleton-based mobs, see #1153
