oPeanutButter Posted April 29, 2012 Posted April 29, 2012 Launcher/pack Version: Technic Launcher 1.0.1.1- (Tekkit) Operating System: Windows 7 64-bit Version of Java: Java JRE6 update 31/ Java JRE7 update 3 Description of Problem: Hi, I'm sorry if this is in the wrong section (and if the description is too long!) but I couldn't decide between Tekkit bugs or just general Tekkit SMP. (Seeing how it's not a Tekkit bug as such.) I have had a Tekkit 1.1 server now for quite some time, but today when I go to start up my server, it wouldn't start up giving me an error which I know the problem to. I uninstalled Java 7 the day before. So, after reinstalling it I went to play on Tekkit and found out that I have terrible lag on both Tekkit SSP and Tekkit SMP. So, I got rid of all of my Java files and started downloading them again so I could see if that fixed it. Nope. I've figured out that if I have Java 7, I can run my server fine and dandy, but Java 7 simply being on my system makes Tekkit unplayable due to horrible lag (1-5 FPS) But on the other hand, if I have only Java 6 on my system, Tekkit will run absolutely perfect but my server will not start up and I get this from the command line: Error Messages: Aliasing material 10 name: lava Aliasing material 11

Milk Posted April 30, 2012 Posted April 30, 2012 Well, there's the easy way, which is to get rid of advanced machines. And then there's the harder way (that I'm not even sure will work), which is to launch your server in java 7 and your client in java 6. I believe this is possible through "Open with" in the right click menu.

I believe this is possible through "Open with" in the right click menu. Just checked if you can open with, and there isn't any option. What is advanced machines anyways? Is it the rotary macerator and so on and on..?
MaliceGrimm Posted May 1, 2012 Posted May 1, 2012 Advanced machines is the Rotary Macerator, Singularity Compressor and Centrifuge Extractor. Easy way to fix is to just disable the mod and run your server on Java 6.
ankz Posted May 5, 2012 Posted May 5, 2012 if you run it with a batch you can do this for the server: "c:\program files\java\jre7\bin\java" -Xmx1G -Xms1G -jar Tekkit.jar nogui and this for the client: "c:\program files\java\jre6\bin\java" -jar Minecraft.exe so you use different paths for jre6 and jre7. have fun!
