Stormman3100 Posted January 9, 2015 Posted January 9, 2015 I am trying to start a tekkit server for 1.6.4 for me and my friend. I click on the Launch.bat file and I get this: C:UsersChristian_2Desktoptekkit>java -Xmx1G -Xms512M -jar Tekkit.jar nogui Jan 08, 2015 10:18:10 PM net.minecraft.launchwrapper.LogWrapper log INFO: Loading tweak class name cpw.mods.fml.common.launcher.FMLServerTweaker Jan 08, 2015 10:18:10 PM net.minecraft.launchwrapper.LogWrapper log INFO: Using primary tweak class name cpw.mods.fml.common.launcher.FMLServerTweak er Jan 08, 2015 10:18:10 PM net.minecraft.launchwrapper.LogWrapper log INFO: Calling tweak class cpw.mods.fml.common.launcher.FMLServerTweaker 2015-01-08 22:18:10 [iNFO] [ForgeModLoader] Forge Mod Loader version 6.4.49.965 for Minecraft 1.6.4 loading 2015-01-08 22:18:10 [iNFO] [ForgeModLoader] Java is Java HotSpot Client VM, version 1.8.0_25, running on Windows 8.1:x86:6.3, installed at C:Program Files (x86)Javajre1.8.0_25 2015-01-08 22:18:10 [WARNING] [ForgeModLoader] The coremod codechicken.core.laun ch.DepLoader does not have a MCVersion annotation, it may cause issues with this version of Minecraft 2015-01-08 22:18:10 [WARNING] [ForgeModLoader] The coremod appeng.transformer.Ap pEngCore does not have a MCVersion annotation, it may cause issues with this ver sion of Minecraft 2015-01-08 22:18:10 [iNFO] [ForgeModLoader] [AppEng] Core Init 2015-01-08 22:18:10 [WARNING] [ForgeModLoader] The coremod calclavia.lib.Calclav iaPluginLoader does not have a MCVersion annotation, it may cause issues with th is version of Minecraft 2015-01-08 22:18:10 [WARNING] [ForgeModLoader] The coremod codechicken.core.laun ch.CodeChickenCorePlugin does not have a MCVersion annotation, it may cause issu es with this version of Minecraft 2015-01-08 22:18:10 [WARNING] [ForgeModLoader] The coremod cofh.asm.LoadingPlugi n does not have a MCVersion annotation, it may cause issues with this version of Minecraft 2015-01-08 22:18:10 [WARNING] [ForgeModLoader] The coremod mods.immibis.microblo cks.coremod.MicroblocksCoreMod does not have a MCVersion annotation, it may caus e issues with this version of Minecraft 2015-01-08 22:18:10 [WARNING] [ForgeModLoader] The coremod logisticspipes.asm.Lo gisticsPipesCoreLoader does not have a MCVersion annotation, it may cause issues with this version of Minecraft 2015-01-08 22:18:10 [WARNING] [ForgeModLoader] The coremod micdoodle8.mods.micco re.MicdoodlePlugin does not have a MCVersion annotation, it may cause issues wit h this version of Minecraft 2015-01-08 22:18:10 [WARNING] [ForgeModLoader] The coremod openmods.OpenModsCore Plugin does not have a MCVersion annotation, it may cause issues with this versi on of Minecraft 2015-01-08 22:18:10 [WARNING] [ForgeModLoader] The coremod codechicken.core.laun ch.DepLoader does not have a MCVersion annotation, it may cause issues with this version of Minecraft 2015-01-08 22:18:10 [WARNING] [ForgeModLoader] The coremod universalelectricity. core.UELoader does not have a MCVersion annotation, it may cause issues with thi s version of Minecraft 2015-01-08 22:18:10 [WARNING] [ForgeModLoader] The coremod codechicken.core.laun ch.DepLoader does not have a MCVersion annotation, it may cause issues with this version of Minecraft 2015-01-08 22:18:10 [iNFO] [ForgeModLoader] Loading tweak class name cpw.mods.fm l.common.launcher.FMLInjectionAndSortingTweaker 2015-01-08 22:18:10 [iNFO] [ForgeModLoader] Loading tweak class name cpw.mods.fm l.common.launcher.FMLDeobfTweaker 2015-01-08 22:18:10 [iNFO] [ForgeModLoader] Calling tweak class cpw.mods.fml.com mon.launcher.FMLInjectionAndSortingTweaker 2015-01-08 22:18:10 [sEVERE] [ForgeModLoader] Unable to launch java.util.ConcurrentModificationException at java.util.ArrayList$Itr.checkForComodification(Unknown Source) at java.util.ArrayList$Itr.remove(Unknown Source) at net.minecraft.launchwrapper.Launch.launch(Launch.java:114) at net.minecraft.launchwrapper.Launch.main(Launch.java:27) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at cpw.mods.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.j ava:48) at cpw.mods.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper. java:17) C:UsersChristian_2Desktoptekkit>pause Press any key to continue . . . I also try to start the Executable Jar File called "Tekkit" but nothing happens other than a file called ForgeModLoader-server-0 and .log.1 appear in the file, but nothing happens after words. What am I doing wrong. If you need more information I can copy and paste whatever you need. Thank You
Curunir Posted January 9, 2015 Posted January 9, 2015 (edited) Please take all issues to the tracker. Make sure to include crash logs. From the launcher log you posted, it seems that two things are going wrong: There seems to be only 512 MiB of RAM allocated to the server, because some system setting is overriding the default allocation. You are running Java 8. The server apparently does not have the hotfix included yet, instructions here. Always use the launch script. Do not try to run the jar files directly.

EvilOwl Posted January 9, 2015 Posted January 9, 2015 There seems to be only 512 MiB of RAM allocated to the server, because some system setting is overriding the default allocation. 1GB (-Xmx1G)
Curunir Posted January 9, 2015 Posted January 9, 2015 I was looking at "-Xms512M". But then again, I have yet to discover what distinguishes Xms and Xmx.
Curunir Posted January 9, 2015 Posted January 9, 2015 Well, these are still not the default values. Tekkit 1.2.9e has these in the launch script: -Xmx3G -Xms2G So the advice remains: Use the launch script, apply the Java fix (or downgrade to Java 7).
