HOOOOOOOOOOOOOOOOOOOLY FUCK i get this too

jesus christ i solved our problem my friend! it has something to do with loading netherores, so go into your mods folder in the tekkit folder thingy and delete (or move for further note) nether ores. I have zero experience with this. yet i managed to unclusterfuck our deals.

"error occurred durring initialization of UM

could not reserve enough space for object heap

could not create the Java virtual machine"

is there anyway to fix this?

Nope. It's impossible to fix, completely, without using the search bar or Google. You should try it sometime.

Google isn't the answer to everything you know...

No, but in this case you would have had an answer far faster, at least enough to know to reduce the memory you're trying to dedicate to the server.

Either some of these people don't know how to use Google or they ACTUALLY live in the past -_-

Some people aren't super tech savvy. They are probably people who just want to play a game with friends but have never touched the actual components of a computer. And google sometimes doesn't help. Hell, I didn't know how to port forward for a good year after I got a router and that's without asking for help, not knowing what I'm doing, and using Google. It's like looking a an engine for a car or a plane with no prior knowledge of anything to do with it. You would be completely lost and wouldn't know where to start. Rather than getting aggravated with them, tell them what to do so they can then pass their knowledge on and so forth.

But the majority of the problems here could have been solved by a 30 second google search?

This isn't how to setup a Tekkit server this is how to fix some random bug. How the hell do I install a tekkit server so me and my friend can play on it? Any guide on that? >_>

I was actually thinking about making a guide that explains everything. But just look up how to portforward. Here's a site to help you http://portforward.com/english/routers/port_forwarding/routerindex.htm I would explain it to you but it's different for everyone. To use the server make sure you download it from the tekkit page, make sure you and your friends are using the same version as the server, then run the launch.bat. Of course do this after you port forward and it should work.

You probably got this solved but in case anyone else encounters it, like I did yesterday, there might be another issue which I never came across while googling.

I have 12GB of RAM, and it wouldn't work, after previously working, following a fresh windows 64bit install. The issue was that my browser (Chrome) is only a 32bit browser and therefore when it went to the Java download page, it automatically assigned me the 32bit version of Java - when I needed the 64bit version to allow it to access all my memory. I needed to go to the manual Java download page (http://www.java.com/en/download/manual.jsp) to get the 64bit version. After that installed it worked without issue.

So, i've done exactly what this told me to, but when i open the .bat file, the cmd screen comes up and says..

C:\users\dj\desktop\tekkitserv>java -Xmx3g -Xms2g -jar Tekkit.jar nogui

Error ovvured during the initialization of VM

Could not reserve enough space for object heap

Error:could not create the Java Virtual Machine.

Error: A Fatal exception has occured. Program will exit.

Read through previous posts before you post a problem. That might help considering I and others have helped this problem multiple times before. Change the 3 and 2 in -Xmx3g and -Xms2g to match the amount of RAM you want to allow Tekkit to use. It can't be more than you have. If that doesn't work make sure you download a 64bit Java if you're on a 64bit OS.
