You've set the default color to be white: anything unsorted will go to white. But you've painted the tube immediately after the sorting machine white, which means that nothing can get to the other colored tubes.

Set connected textures to Fast, that also helps, and set terrain textures off. That should restore normality.

It sometimes helps Java run more smoothly to have both, but if your computer is x86 it is 64 bit.

Try and tone down your graphics settings. Optifine has loads of cool tweaks to enable Tekkit to run faster. Disabling animations and terrain textures helps, as well as turning down render distance and setting graphics to 'Fast'.

Trust that the server launcher does things correctly the first time. It usually does.

What does it say specifically? Do any error messages come up, or does it just not install the mods?

This is almost definitely a Java problem, or a OS error causing Java to crash. This has nothing to do with Tekkit. Firstly, delete all versions of Java and then install both the 32 and 64 bit versions of Java. If this doesn't rectify the issue, pursue investigations with Java themselves.

I am helping someone with a similar problem. My main recommendation is to either remove Tekkit Restrict entirely, or to disable chunk unloader and inventory throttle. This might fix this problem. You can see my other recommendations for someone who has a similar problem here: http://forums.technicpack.net/threads/reached-end-of-stream-read-timed-out-crashing-the-tekkit-paying-5.34423/#post-291039 This is starting to appear more and more, and generally on large servers. Perhaps the amount of players is overloading the server in some way?

When using hamachi, you have to make sure: 1. You are both on the same Hamachi network. 2. Both of you have Hamachi running while on Tekkit. 3. Hamachi isn't being blocked by firewalls. P.S. Port 25564 should be fine.

This is an IC2 API issue. Luckily there is a fix. Download link to the fix is here (zip file): http://ge.tt/7Gc1l7S/v/1 To fix the IC2 Tekkit 3.1.3 crashing, do the following: 1. Stop your Tekkit 3.1.3 server (if not already stopped...or crashed ) 2. Go to your Tekkit server mods folder 2. Find the file called: "industrialcraft2-1.103-mcpc1.2.5r2.zip" 3. Open the zip file and go into the ic2/api directory (no need to decompress it - just edit directly) 4. Delete ElectricItem.class, EnergyNet.class, and NetworkHelper.class 5. Download the class fix .zip in the above link 6. Copy the 3 classes from the downloaded zip and paste them into ic2 zip api folder where you just deleted the others 7. Close your ic2 zip and start your server. It should no longer crash relating to this specific interface fix. (It may crash for other reasons, however.) [NOTE: This change is only for 3.1.3 installs, not 3.1.2] Thanks to Tekkitopotamus for the fix. The Power pipe thing I've not seen before however. It might be fixed once you have implemented the above changes.

This is might be a windows 8 issue, since most of the time chunks load fine. Please look at the server log and post it here. It should tell you if the server is loading the world incorrectly.

Don't unzip the mods!!!!

Yes, the railcraft mod was updated in the latest build of Tekkit. This problem however is rather strange. Apparently, Railcraft has confused the Block ID's. No, there is no way to fix this unless you restore your server to 3.1.2 and use a previous world backup.

If a mod is not working properly and conflicting with your world, it could be doing this, and a server prompt will tell you exactly what is up. These thing affect random players at random times. You could reinstall Tekkit, like I suggested, and start a new world. If this doesn't clear up your lag, its your computer that's causing the issues.

It sounds contradictory, but try allocating less memory to Tekkit. 2 GB should be fine. I don't know why, but this sometimes works in clearing this up. Also, it might be your world that is doing this. That Blaze-Rod machine for instance, is resource-intensive. If you can before the lag hits, turn all your machines off. Also, one of your machines might have overloaded and be dropping items all over the place. Use MCedit to delete entities, this might restore normal working order to your world.

This is why I prefer hosting my own servers, so I know that if something goes wrong I can fix it. I think your server is contradicting itself here, causing a crash. Its a pain, but you may have to get in contact with Nitrado and tell them you are restarting your server because it has crashed out. Of course, this could be their fault too, if their servers are malfunctioning in some way.

[sEVERE] A critical error has occurred. java.lang.ArrayIndexOutOfBoundsException: 4 at railcraft.common.utility.TileUtilityItem.a(TileUtilityItem.java:61) at railcraft.common.utility.TileMultiBlock.a(TileMultiBlock.java:250) at railcraft.common.utility.TileMultiBlock.a(TileMultiBlock.java:254) at railcraft.common.api.InventoryMapper.a(InventoryMapper.java:46) at railcraft.common.api.InventoryTools.moveOneItem(InventoryTools.java:375) at railcraft.common.utility.TileItemLoader.moveItemToCart(TileItemLoader.java:252) at railcraft.common.utility.TileItemLoader.n_(TileItemLoader.java:203) at xd.n(World.java:2081) at net.minecraft.client.Minecraft.k(Minecraft.java:1871) at net.minecraft.client.Minecraft.x(Minecraft.java:825) at net.minecraft.client.Minecraft.run(Minecraft.java:753) at java.lang.Thread.run(Unknown Source) This looks like the Item Loader.class has been corrupted in some way. Railcraft is notorious for being susceptible to file corruption caused by server crashes. To fix this, you should back-up your texture-packs and your worlds, delete your server folder and then recreate the server, adding your worlds and texturepack back in. With a fresh install of Railcraft, this error should be rectified.

I used to get this for my custom Tekkit server, in relation to Transformers. Essentially, the problem is that the block in question is confusing the server by not functioning as the server expects, so the server resets the block, however it still doesn't function correctly, thus spamming the console. The mod itself works, but if you want to get rid of the spam, delete all powerconverter related blocks and exit the server. Then, delete the mod from the server files, and launch the server again. It will now work normally. Finally, close the server again, and put the powerconverters mod back in the server files. Then run the server again, and it should work fine.

It is possible that the installation of Tekkit Lite has changed the configuration of your java somehow. Try reinstalling java 32 and 64 bit versions (delete the old ones first) and see if that works.

Firstly java needs to be updated to 64 bit ASAP. What you've just said isn't helpful at all. Can you provide an error log please, of what the server came back said when it crashed. This way I'll be able to figure out what exactly is going on.

Are you sure the server log doesn't say anything specific? If it only happens when the server starts, it means the server is interacting with the world when it shouldn't be, or its reading the level.dat file wrongly, and therefore loading the world incorrectly. There's a generally a reason why it does so, and if there is a reason it appears on the log, and if it appears on the log its fixable!

This is a buildcraft error. Some of the files are corrupted in some way. Get your friend to back-up his worlds, and then create a new server. Its a bit of a hassle I know but it should work properly after re-downloading the Buildcraft mod for the server. Also, re-download your tekkit files.

This is an issue the Technic Pack team addressed the other day. Delete the launcher and all the files associated with Tekkit, re download the Technic Launcher and run it. It should now work.

This is either a very bad java malfunction, or a Windows error. I tend to think the latter. Firstly, reinstall both 32 and 64 bit versions of java (make sure you delete the other ones first) and try again. If the same error is returned, something Windows is doing means it cannot run java correctly. This might be solved if you (re)install C++ , as it is a necessary component for running java binaries. Otherwise, you will need to talk to someone whose better with Vista and Microsoft Windows in general than me.

The server crash has corrupted the wireless redstone mod. Is there any wireless redstone in your world? Use MCedit to delete all wireless redstone blocks, then move the world into a fresh server, only keeping the server.PROP file (not the config file). This should fix the problem.
