Have you been able to make any builds at all? Does this error occur when making a new build for a specific pack or all packs?

Sounds like an opportunity for you to shine and make that pack!

-XX:MaxPermSize=7g Why on earth would you try to allocate 7G of RAM to Permanent Generation space? 256M is probably fine, and a much better place to start. You need to update to the latest version of MobiusCore: http://minecraft.curseforge.com/mc-mods/76734-mobiuscore/files You need to use this version of Opis: https://www.dropbox.com/s/4vlbe4zpkk6x50q/Opis_1.2.2b_test1.zip Update those and come back if you are still having problems.

Don't bump your posts. If someone is available to help they will do so. You may get more assistance in the Tekkit Classic discussion forum: http://forums.technicpack.net/forum/10-tekkit-classic-discussion/

Your CodeChickenCore mod does not match the version of NEI you have. Always get mods from their authors and make sure you get matching mods and dependencies. Reading through this may help you: The default generated config files for your mods have some item ID conflicts. Search the ForgeModLoader-client-0.log for the word CONFLICT. Since OceanCraft mod has no config file (poorly coded mod) you will have to change the config files of other mods to accommodate OceanCraft IDs. Your modpack has no config files. Always include the config files from your local test environment after you get the pack working and all conflicts resolved.

You have not provided enough information: What modpack are you using (provide a link). For most custom pack issues one would follow up with the pack author for problems specific to the modpack. Does the custom pack not work while the built-in packs from Technic work fine? If the built-in packs do not work then this issue belongs in the Tracker (link at top of this page). Please provide crash reports from the modpack.

It is the same as vanilla MC, just more so. Modded MC (Forge) requires more CPU and more RAM. Some folks have some success adding OptiFine to their client modpacks: https://optifine.net/home

Add "?download=1" (without quotes) to the end of the URL.

Server down (on either port). Website non-functional.

@OP: This belongs in Server Op Swap Shop @DragonsBane725: You almost surely do not have the same exact problem as OP. Start a new thread with specifics (including modpack link) in Server Op Swap Shop.

Make sure you address those item ID conflicts. With that many conflicts there will be numerous and common issues with multiple mods.

Problem likely belongs in the BTeam Tracker. (see link at top of page)

All of the Technic packs have a server download. Inside that download will be a batch file used to start their server. Just copy one of those files and change the name of the JAR that is executed (after the "-jar") to reference your Cauldron JAR.

Client pack: You have too much stuff in your bin folder. The bin folder should only contain modpack.jar. Remove the other files/folders. You have about 30 item ID conflicts in your pack. These MUST be resolved before trying to make a server for the pack. Some of your mods are oddly named. The implication is that you are not getting the mods from their respective author's or that you are renaming them for some reason. I recommend reading this: Client only mods which must be removed on the server: ArmorStatusHUD OptiFine Zan's Minimap

This belongs in the Tracker for Tekkit Lite (see the link at the top of the page).

You need to contact copy.com and ask them why your file is being flagged: {"result":"error","error_code":"1048","error_string":"Link 'dXUXhaLm8pkq' has been flagged as abuse"} If your files are repeatedly being flagged for abuse then you have problems we cannot help you with. You need to contact copy.com.

That error looks like you may have a client-only mod in your server mods folder. Please provide a link to your Technic pack page or API URL and we can tell you which mods must be removed from the server.

Yes, your own server.dat file. Just make sure only the servers you wish to be listed are in your client then copy out the server.dat file and include it in your pack.

When requesting help for a modpack one must always provide a link to the Technic pack page or API URL.

You don't "click" the Cauldron JAR file. You execute it using Java with some fixed parameters, like so: java -Xmx2048m -Xms2048m -XX:PermSpace=256m -jar cauldron-blah-blah-blah.jar

You are missing libraries: https://copy.com/qLsTvZfUUkkb?download=1

The cauldron-whatever.jar file which comes out of the installer.

A server does not use a "bin" folder at all. It only uses the JAR file you run to start the server. If you tell the Cauldron installer to "extract" it will only place the server JAR file into your folder. If you tell it to "install" it will place the server JAR file into your folder AND download all the required libraries into your folder. You want to "install".

Your required "bin" folder is actually named "Bin". Take note of the capital "B". This folder name must be all lower case. You have OpenBlocks mod but not the dependency mod OpenModsLib. Your versions of RotaryCraft (older) and the required dependency mod DragonAPI (newer) do not match. Always get matching mods and dependencies. Follow the mod author's instructions. The version of IndustrialCraft 2 you have is not compatible with your pack version and other mods. Read this post: Your Reliquary mod is out of date and incompatible with other mods. It is also named oddly indicating that you did not get the file from the author's preferred distribution channels. I recommend reading through this post: Your version of Quarry Plus mod is out of date and not compatible with other mods. Your version of DyeTrees (older) and the required dependency mod DragonAPI (newer) do not match. You need to manually update your ForgeMultipart (in mods1.6.4) to the latest version. Calclavia's Atomic Science is now part of Resonant Induction. You need to remove Atomic Science and Calclavia Core mods before adding Resonant Induction Core and it's child mods. DyeTrees mod has a biome ID conflict on ID 48 with Biomes O' Plenty. Change the DyeTrees config from ID 48 to 117 (or any other open ID). DyeTrees mod has an item ID conflict for ID 13000 which must be fixed. Item ID 7595 seems to be open. You have multiple block ID conflicts between various mods. Once you fix all the preceding bullet points the client will kick out an IDConflicts.txt file with details. Resonant Induction mod has multiple block ID conflicts which aren't triggering the creation of the IDConflicts.txt file. Edit the default Resonant Induction.cfg file and replace all instances of "=12" with "=18" to switch the block IDs from the 1200's to the 1800's which is an open ID range. You have multiple serious item ID conflicts which must be resolved. Once the pack starts successfully examine your ForgeModLoader-client-0.log file for the word CONFLICT. Ignore the MystCraft conflicts (that mod is doing something odd and those are false positives), but fix the remaining instances. A few items of note: I provided the link to my "Getting Mods" post above, but it is important enough that I'll mention it again. It is vital that one follows the mod author's instructions when installing mods, and that mods with dependencies are installed together with their correctly matching versions. Dropping in a ton of mods from different authors at the same time is a recipe for frustration. Add mods in systematically and in logical groups (mods with dependencies, mods as collections i.e. Resonant Induction, etc.) and test the pack. If it doesn't work check your ForgeModLoader-client-0.log file for additional context as the crash report is often lacking. Fix these issues and come back if you are still having difficulties.

Client pack (items in bold are still unfixed from initial response): The bin folder should only contain the file "modpack.jar". This file is the Forge universal binary JAR file renamed to be "modpack.jar". You should not include the modsrei_minimap folder. This contains waypoints and such for you personally and should not be distributed.
