I have a 1.5.2 instance of minecraft with 79 mods, and after about 15 minutes of being in-world, it starts lagging regularly, then after 3 or 4 increasingly severe freezes, it crashes. It is rare to have any crash at all, but I have a crash log from MultiMC. Here is the first part, with a mod list and the entire log of what went on before the crash: http://pastebin.com/v8nVLSqp. Here is the error that actually caused the crash, for convenience: 2013-05-21 21:24:51 [iNFO] [sTDERR] java.lang.NoClassDefFoundError: net/minecraft/world/CallableLvl2 2013-05-21 21:24:51 [iNFO] [sTDERR] at net.minecraft.world.World.func_72914_a(World.java:4398) 2013-05-21 21:24:51 [iNFO] [sTDERR] at net.minecraft.server.MinecraftServer.func_71190_q(MinecraftServer.java:657) 2013-05-21 21:24:51 [iNFO] [sTDERR] at net.minecraft.server.MinecraftServer.func_71217_p(MinecraftServer.java:571) 2013-05-21 21:24:51 [iNFO] [sTDERR] at net.minecraft.server.integrated.IntegratedServer.func_71217_p(IntegratedServer.java:171) 2013-05-21 21:24:51 [iNFO] [sTDERR] at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:469) 2013-05-21 21:24:51 [iNFO] [sTDERR] at net.minecraft.server.ThreadMinecraftServer.run(SourceFile:573) 2013-05-21 21:24:51 [iNFO] [sTDERR] Caused by: java.lang.ClassNotFoundException: net.minecraft.world.CallableLvl2 2013-05-21 21:24:51 [iNFO] [sTDERR] at cpw.mods.fml.relauncher.RelaunchClassLoader.findClass(RelaunchClassLoader.java:238) 2013-05-21 21:24:51 [iNFO] [sTDERR] at java.lang.ClassLoader.loadClass(Unknown Source) 2013-05-21 21:24:51 [iNFO] [sTDERR] at java.lang.ClassLoader.loadClass(Unknown Source) 2013-05-21 21:24:51 [iNFO] [sTDERR] ... 6 more 2013-05-21 21:24:51 [iNFO] [sTDERR] Caused by: java.lang.OutOfMemoryError: PermGen space 2013-05-21 21:24:51 [iNFO] [sTDERR] at java.lang.ClassLoader.defineClass1(Native Method) 2013-05-21 21:24:51 [iNFO] [sTDERR] at java.lang.ClassLoader.defineClass(Unknown Source) 2013-05-21 21:24:51 [iNFO] [sTDERR] at java.security.SecureClassLoader.defineClass(Unknown Source) 2013-05-21 21:24:51 [iNFO] [sTDERR] at cpw.mods.fml.relauncher.RelaunchClassLoader.findClass(RelaunchClassLoader.java:227) 2013-05-21 21:24:51 [iNFO] [sTDERR] ... 8 more 2013-05-21 21:24:53 [iNFO] [Minecraft-Server] Stopping server 2013-05-21 21:24:53 [iNFO] [Minecraft-Server] Saving players 2013-05-21 21:24:53 [iNFO] [sTDOUT] Unloading Player: <username> 2013-05-21 21:24:53 [iNFO] [Minecraft-Server] Saving worlds 2013-05-21 21:24:53 [iNFO] [Minecraft-Server] Saving chunks for level 'Test'/Overworld 2013-05-21 21:25:22 [iNFO] [Minecraft-Server] Saving chunks for level 'Test'/Nether 2013-05-21 21:25:22 [iNFO] [ForgeModLoader] [Thaumcraft] Removed 24 aura nodes when world 0 unloaded. 2013-05-21 21:25:23 [iNFO] [ForgeModLoader] [Thaumcraft] Removed 0 aura nodes when world -1 unloaded. 2013-05-21 21:25:23 [iNFO] [ForgeModLoader] Unloading dimension 0 2013-05-21 21:25:23 [iNFO] [ForgeModLoader] Unloading dimension -1 2013-05-21 21:25:24 [sEVERE] [ForgeModLoader] Fatal errors were detected during the transition from SERVER_STARTED to SERVER_STOPPED. Loading cannot continue If anyone could help me track down the problems, that would be fantastic. EDIT: I have also noticed that right before it is about to crash, my computer starts to "freak out." Usually, the processor runs at about 30% while playing minecraft, but when it crashes, it jumps to about 90%, until it finally gives up and stops.

Oh well

Thanks! I completely reinstalled both the JRE and the JDK from scratch, as well as added it to the path variable, and the installer ran without a hickup! Who know what the problem really was, but I'm just glad it works now.

This post is very helpful, it will be good to keep in mind, especially the door timer part... I may have to adjust some things to deal with that. Thanks!

Not entirely sure, but it seems like it could be a problem that I don't have anything pertaining to Java in my Path variable? I'm not sure if I'm looking in the right place, but it says nothing about Java anywhere in it... This sounds like something I should probably Google to set up?

Thanks for trying!

If you would be willing to do that, I would LOVE to see an explanation of the Villager code! It would be incredibly helpful for many minecraft-related projects, modding and otherwise.

When I open Java settings in my control panel it pulls up a very simplistic control panel with 4 tabs, General, Java, Security, and Advanced. Under the Java tab, there is a runtime environment settings dialog box, and under system there is a check next to Java 1.7.0_10, pathed to C:\program files\Java\jre7\bin\javaw.exe

I can read the error. I found the class in forge\fml\common\cpw\mods\fml\common\asm\transformers. Is this where it is supposed to be found?

So I take it no-one has any ideas? I'd really like to get into modding, but at the moment have no idea how to properly de-compile minecraft...

I am trying to use the install.cmd in minecraft forge, but I keep getting this error: ================ Forge ModLoader Setup Start =================== Downloaded mcp7.44.zip Extracting MCP to 'C:\Users\Grey\Documents\Development\MCP\forge\mcp' Setting up MCP Backing up commands.py patching file commands.py Commands patch applied successfully Copying FML conf Creating re-packaged srg Creating re-packaged exc Creating re-packaged MCP patches Fixing MCP Workspace Downloaded argo-3.2-src.jar Downloaded guava-14.0-rc3.jar Downloaded asm-4.1.tar.gz Downloaded asm-debug-all-4.1.jar Downloaded bcprov-debug-jdk15on-148.jar Downloaded bcprov-jdk15on-148-src.zip Downloaded guava-14.0-rc3-sources.jar Downloaded lwjgl.jar Downloaded lwjgl_util.jar Downloaded jinput.jar Downloaded windows_natives.jar Extracting jinput-dx8.dll Extracting jinput-dx8_64.dll Extracting jinput-raw.dll Extracting jinput-raw_64.dll Extracting lwjgl.dll Extracting lwjgl64.dll Extracting OpenAL32.dll Extracting OpenAL64.dll Downloaded macosx_natives.jar Extracting libjinput-osx.jnilib Extracting liblwjgl.jnilib Extracting libopenal.dylib Extracting openal.dylib Downloaded linux_natives.jar Extracting libjinput-linux.so Extracting libjinput-linux64.so Extracting liblwjgl.so Extracting liblwjgl64.so Extracting libopenal.so Extracting libopenal64.so Downloaded minecraft.jar Downloaded minecraft_server.jar == MCP 7.44 (data: 7.44, client: 1.5.1, server: 1.5.1) == > Searching for javac.exe in C:\Program Files # found ff, ff patches, srgs, name csvs, doc csvs, param csvs, renumber csv, ast yle, astyle config > Creating Retroguard config files == Decompiling client using fernflower == > Creating SRGs > Applying Retroguard > Compiling AccessTransformer > Compiling MCPMerger > Running MCPMerger Error: Could not find or load main class cpw.mods.fml.common.asm.transformers.MC PMerger Decompile Exception: 1 Press any key to continue . . .
