Recently my server seems to get a problem after running for some hours. If i start it everybody can connect.. then after a while it gives an error when trying to connect: [21:45:54] [Server thread/WARN] [minecraft/NetworkSystem]: Failed to handle packet for /xx.xxx.xx.xxx:xxxxx java.lang.NullPointerException: null at dev.ftb.mods.ftbessentials.net.UpdateTabNamePacket.write(UpdateTabNamePacket.java:44) ~[ftbessentials:1605.1.4-build.13] {re:classloading} at dev.ftb.mods.ftblibrary.net.snm.BasePacket.toPacket(BasePacket.java:20) ~[ftblibrary:1605.3.1-build.56] {re:classloading} at dev.ftb.mods.ftblibrary.net.snm.BaseS2CPacket.sendTo(BaseS2CPacket.java:21) ~[ftblibrary:1605.3.1-build.56] {re:classloading} at dev.ftb.mods.ftbessentials.util.FTBEPlayerData.sendTabName(FTBEPlayerData.java:186) ~[ftbessentials:1605.1.4-build.13] {re:classloading} at dev.ftb.mods.ftbessentials.FTBEEventHandler.playerLoggedIn(FTBEEventHandler.java:80) ~[ftbessentials:1605.1.4-build.13] {re:classloading} at net.minecraftforge.eventbus.ASMEventHandler_24_FTBEEventHandler_playerLoggedIn_PlayerLoggedInEvent.invoke(.dynamic) ~[?:?] {} at net.minecraftforge.eventbus.ASMEventHandler.invoke(ASMEventHandler.java:85) ~[eventbus-4.0.0.jar:?] {} at net.minecraftforge.eventbus.EventBus.post(EventBus.java:302) ~[eventbus-4.0.0.jar:?] {} at net.minecraftforge.eventbus.EventBus.post(EventBus.java:283) ~[eventbus-4.0.0.jar:?] {} at net.minecraftforge.fml.hooks.BasicEventHooks.firePlayerLoggedIn(BasicEventHooks.java:44) ~[forge:?] {re:classloading} at net.minecraft.server.management.PlayerList.func_72355_a(PlayerList.java:231) ~[?:?] {re:mixin,pl:accesstransformer:B,pl:runtimedistcleaner:A,re:classloading,pl:accesstransformer:B,pl:mixin:APP:libx.mixins.json:MixinPlayerList,pl:mixin:APP:dpanvil.mixins.json:MixinPlayerList,pl:mixin:APP:assets/botania/botania.mixins.json:MixinPlayerList,pl:mixin:A,pl:runtimedistcleaner:A} at net.minecraft.network.login.ServerLoginNetHandler.func_147326_c(ServerLoginNetHandler.java:118) ~[?:?] {re:mixin,re:classloading,pl:mixin:APP:randompatches.mixins.json:timeouts.ServerLoginNetHandlerMixin,pl:mixin:A} at net.minecraft.network.login.ServerLoginNetHandler.func_73660_a(ServerLoginNetHandler.java:65) ~[?:?] {re:mixin,re:classloading,pl:mixin:APP:randompatches.mixins.json:timeouts.ServerLoginNetHandlerMixin,pl:mixin:A} at net.minecraft.network.NetworkManager.func_74428_b(NetworkManager.java:222) ~[?:?] {re:classloading,pl:runtimedistcleaner:A,re:mixin,pl:runtimedistcleaner:A} at net.minecraft.network.NetworkSystem.func_151269_c(NetworkSystem.java:134) ~[?:?] {re:classloading,pl:runtimedistcleaner:A} at net.minecraft.server.MinecraftServer.func_71190_q(MinecraftServer.java:865) ~[?:?] {re:mixin,pl:accesstransformer:B,pl:runtimedistcleaner:A,re:classloading,pl:accesstransformer:B,pl:mixin:APP:byg.mixins.json:server.MixinMinecraftServer,pl:mixin:APP:resourcefulbees.mixins.json:MixinMinecraftServer,pl:mixin:APP:elementalcraft.mixins.json:MixinMinecraftServer,pl:mixin:APP:kubejs-common.mixins.json:MinecraftServerMixin,pl:mixin:A,pl:runtimedistcleaner:A} at net.minecraft.server.dedicated.DedicatedServer.func_71190_q(DedicatedServer.java:291) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.func_71217_p(MinecraftServer.java:787) ~[?:?] {re:mixin,pl:accesstransformer:B,pl:runtimedistcleaner:A,re:classloading,pl:accesstransformer:B,pl:mixin:APP:byg.mixins.json:server.MixinMinecraftServer,pl:mixin:APP:resourcefulbees.mixins.json:MixinMinecraftServer,pl:mixin:APP:elementalcraft.mixins.json:MixinMinecraftServer,pl:mixin:APP:kubejs-common.mixins.json:MinecraftServerMixin,pl:mixin:A,pl:runtimedistcleaner:A} at net.minecraft.server.MinecraftServer.func_240802_v_(MinecraftServer.java:642) ~[?:?] {re:mixin,pl:accesstransformer:B,pl:runtimedistcleaner:A,re:classloading,pl:accesstransformer:B,pl:mixin:APP:byg.mixins.json:server.MixinMinecraftServer,pl:mixin:APP:resourcefulbees.mixins.json:MixinMinecraftServer,pl:mixin:APP:elementalcraft.mixins.json:MixinMinecraftServer,pl:mixin:APP:kubejs-common.mixins.json:MinecraftServerMixin,pl:mixin:A,pl:runtimedistcleaner:A} at net.minecraft.server.MinecraftServer.func_240783_a_(MinecraftServer.java:232) ~[?:?] {re:mixin,pl:accesstransformer:B,pl:runtimedistcleaner:A,re:classloading,pl:accesstransformer:B,pl:mixin:APP:byg.mixins.json:server.MixinMinecraftServer,pl:mixin:APP:resourcefulbees.mixins.json:MixinMinecraftServer,pl:mixin:APP:elementalcraft.mixins.json:MixinMinecraftServer,pl:mixin:APP:kubejs-common.mixins.json:MinecraftServerMixin,pl:mixin:A,pl:runtimedistcleaner:A} at java.lang.Thread.run(Unknown Source) [?:1.8.0_301] {} Can somebody decipher this, or know a fix for this kind of issue?
