So i know how to fix this memory leak, but it isnt working. I will allocate 6 gb of free mem and it still tells me out of memory. I posted this on minecraft forums but the people there arent too good with nix stuff so ima copy and past my other thread from there below. Any help is awesome :-)

So i was getting the out of memory error, so i edited how i launch to this,

$ java -Xmx2500M -Xms2500M -jar /home/elliott/minecraft.jar

It worked without sound until i uinstalled a texture pack, now my game crashes on launch or after logging in. Here is what terminal says. If you need full bug report, let me know it is about 90 lines long though.

$ java -Xmx2500M -Xms2500M -jar /home/elliott/minecraft.jar

Specs:
os: ubuntu 10.04 gnome 1
8 gb of ram
nvida geforce 460 gtx
intel i5 @3.8 ghz
plenty of hdd space and my swap space if 5 gb ( i thought that wouldn't matter but it did say it might be to small)

Thanks in advance. I have full error report if needed.


Edit:
I reinstalled java now and i cant run minecraft with to much mem. It says it cannot rescue enough. I will box all i did below:

I think the reason it's failing in your edit is that you are giving it too much max heap - more than the (32bit, by the looks of it) JVM can offer. Try bringing the -Xmx down to about 2Gb and -Xms to about 500Mb and see if that works.

If dropping the max/min heap sizes you are requesting for the JVM results in OutOfMemoryExceptions getting thrown again you will know that that was the problem.

It might just be that minecraft requires more heap space than is available to a 32bit JVM. (remember: the amount of heap space available to the code running in the JVM is [significantly] smaller than the amount addressable by the OS. Might even be as low as 2Gb on Ubuntu 10.04). Try installing a 64bit JVM (if your OS is 64bit) and giving it more memory again.

Ok i did what you said. It worked onces i turned down the render distance to medium. Eventually i did get a crash. Here is what i got

I have a 64 bit processor but i am running 32 bit ubuntu. I guess the only way to install 64 bit java would be in virtual box? Or re installing my os.....?

If you don't mind me asking, why do you have x86 bit copy installed on a x64 bit machine? I would just reinstall x64 Ubuntu on the machine and install a x64 bit JVM.
