My brother just got Minecraft. Unfortunately, there appears to be some form of memory leak.
For about fifteen minutes, it runs fine. But then, it shuts off completely. No warning, nothing. The map is deleted on startup.
It is a Lenovo laptop (Y650) and partitioned into three sections (ubuntu, windows 7 [the OS on which he plays it] and a lenovo data partition). It has three gigs of ram, 64-bit. The graphics card runs the game fine. 2.4 Ghz processor.
My computer is worse than his (except it's not partitioned, so could that be the error?) and it runs the game fine.

Please help. I'm thinking it might be a memory leak, but I have no idea how to fix it.

sounds more like the processor is overheating, im running 1 gigs of ram on my netbook and never had anything like that happen and ive played for hours at a time

does it make a whiring noise, beep (if ur sounds on) n then die?)

It shuts off completely. No sound, nothing. So I guess it's not a processor problem. After all, mine's worse than his and runs fine...
The same thing happened when I tried to run an older version on his laptop a while back, so it isn't a problem with the client, as far as I know.

no whiring? thas unusual...... by whiring i mean the sound of a fan when its being noisy

oh well my advise is still good idea to follow, tends to make laptops n computers run better anyway

Nope. No whirring at all. I guess I could get him to try it... But I'm not sure it will help much...

have you tried running the game in ubuntu?

Okay, he (finally) got around to trying it, and got this:

... I have no idea what it means.

A computer shutting down when running a CPU intensive application is usually caused by an overheating CPU.

I'd recommend downloading speedfan (free software) to monitor temperatures before and after opening the game.

Do you mean the whole computer shuts down or just the game itself shuts down? The people telling you it is a CPU overheating are saying this because they think you mean the whole computer.

The whole computer shuts down completely, so it may be overheating after all. Unfortunately, my brother has a severe case of laziness.

Okay, we're monitoring it now.
The Memory usage has been going up steadily, and went up about a gig.
The GPU is 101C, Core 0: 97C, Core 1: 95C.
It's heated up considerably.
CPU usage is around 70%... Climbing.
Heat's climbing as well. It's been going longer than usual, but at this rate it will crash.
Memory usage has stopped at 2.04 GB. It's pretty stable. Heat is staying around 100C. It should've crashed by now, but hasn't...
