Scrotty

Any suggestion on which one I should remove first? Pixelmon is the main mod, I'm not using the recommended Forge version for the mod but that version is not server friendly. Immense console spam, which was fixed in a later version but the mod still hasn't updated to it. I'm using the latest recommended version for my server. Another mod I really hope it isn't is ModControl, because it blocks any client side mods except those I permit..

If multiple users connecting to a server are using a different Forge version could it cause crashing? Either that or the server mods are my amateur theories. Crash reports appear to be differ but here's one...it crashes often.. ---- Minecraft Crash Report ---- // Don't be sad, have a hug! <3 Time: 6/24/15 10:38 PM Description: Exception in server tick loop java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextNode(HashMap.java:1429) at java.util.HashMap$KeyIterator.next(HashMap.java:1453) at net.minecraft.entity.EntityTracker.func_72788_a(EntityTracker.java:270) at net.minecraft.server.MinecraftServer.func_71190_q(MinecraftServer.java:716) at net.minecraft.server.dedicated.DedicatedServer.func_71190_q(DedicatedServer.java:364) at net.minecraft.server.MinecraftServer.func_71217_p(MinecraftServer.java:598) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:478) at java.lang.Thread.run(Thread.java:745) A detailed walkthrough of the error, its code path and all known details is as follows: --------------------------------------------------------------------------------------- -- System Details -- Details: Minecraft Version: 1.8 Operating System: Windows 8.1 (amd64) version 6.3 Java Version: 1.8.0_45, Oracle Corporation Java VM Version: Java HotSpot(TM) 64-Bit Server VM (mixed mode), Oracle Corporation Memory: 1997176288 bytes (1904 MB) / 3126853632 bytes (2982 MB) up to 3126853632 bytes (2982 MB) JVM Flags: 2 total; -Xms3G -Xmx3G IntCache: cache: 0, tcache: 0, allocated: 13, tallocated: 95 FML: MCP v9.10 FML v8.0.99.99 Minecraft Forge 11.14.3.1450 10 mods loaded, 10 mods active States: 'U' = Unloaded 'L' = Loaded 'C' = Constructed 'H' = Pre-initialized 'I' = Initialized 'J' = Post-initialized 'A' = Available 'D' = Disabled 'E' = Errored UCHIJAAAA mcp{9.05} [Minecraft Coder Pack] (minecraft.jar) UCHIJAAAA FML{8.0.99.99} [Forge Mod Loader] (forge-1.8-11.14.3.1450-universal.jar) UCHIJAAAA Forge{11.14.3.1450} [Minecraft Forge] (forge-1.8-11.14.3.1450-universal.jar) UCHIJAAAA k4lib{1.8-1.0.4} [K4Lib] (k4lib-1.8-1.0.4-universal.jar) UCHIJAAAA colorchat{1.8-1.0.3} [ColorChat] (colorchat-1.8-1.0.3-universal.jar) UCHIJAAAA landdefender{0.4.0} [Land Defender] (landdefender-0.4.0.jar) UCHIJAAAA ModControl{1.4} [Mod Control] (ModControl-1.4.jar) UCHIJAAAA pixelmon{4.0.5} [Pixelmon] (Pixelmon-1.8-4.0.5-universal.jar) UCHIJAAAA SpawnCommands{2.2.0} [spawnCommands] (SpawnCommands-2.2.0-mc1.8-forge.jar) UCHIJAAAA worldedit{6.1} [WorldEdit] (worldedit-forge-mc1.8-6.1.jar) Loaded coremods (and transformers): Profiler Position: N/A (disabled) Player Count: 6 / 20; [EntityPlayerMP['Master_Yen'/1148, l='world', x=198.51, y=73.31, z=-161.51], EntityPlayerMP['David8505'/1582, l='world', x=142.06, y=76.02, z=286.19], EntityPlayerMP['iiFazedPvP'/3275, l='world', x=303.23, y=67.02, z=283.55], EntityPlayerMP['ThePizzaDinosaur'/41252, l='world', x=372.61, y=83.00, z=224.40], EntityPlayerMP['Hydra_of_Death'/4722, l='world', x=267.92, y=64.00, z=248.37], EntityPlayerMP['tubs787'/43169, l='world', x=359.50, y=72.00, z=242.07]] Is Modded: Definitely; Server brand changed to 'fml,forge' Type: Dedicated Server (map_server.txt)
