It seems many users of Minecraft (which runs in Java) are experiencing intermittent freezes and/or erroneous delays in frame rates while playing the game. Other symptoms include the processor (or processor cores) maxing out to 100% CPU cycles.
On my son's AMD, AM2, 3.2GHz 3000+ with 4GB RAM running Windows 7, 32bit or 64bit this problem kept occurring.
The cause seemed to be due to the overclocked processor heating up. The system would then shut down part of the processor or throttle it back in some way to prevent overheating. The apparent %CPU load would then jump from ~30-40% to ~100% and the Java app (in this case Minecraft) would stall.
I tried all the software hacks but with no luck. I did find a post somewhere else that mentioned slowing down the cpu will fix the problem. So this is just a reminder post for everyone......
The fix:
Reduce the clock speed of the processor. To do this you have to enter the Bios setup of the computer and re-clock the processor speed down by 10-20%. In my particular case I set the speed down to 2.4 GHz. In my BIOS settings, I had the option to use a 200MHz clock speed with a "x 12" multiplier. The game ran a few percent slower but without any more freezes.
