Swappiness issues

  • 772

I just got an old laptop, and I am using it to run a minecraft server, just for the fun, but the problem is it only has got 2gbs of ram, I made a 20gb swap section, set swappiness to 100, but I still get my ram stuffed, and when I tested it with an heavy load, my ram still got filled and the laptop froze up, cant I say to a program or something to use swap only? Or atleast say it should use no more that x ammount of ram?

Thanks in advance

sys ubuntu 11.10 2ghz dual core 2gb ram

    • When you are running your ubuntu server are you running it with an X server? If possible dont just reinstall it and tell it to boot without X. It will save you lots of RAM. A headless server will run considerably smoother.
    • What command are you using to run your JVM (Java Virtual Machine) aka the Minecraft server. Specifying the correct amount of RAM in your command may save you trouble. You may be giving it to much.
    • Swap space wont help you with running a Minecraft server. HDD is just not fast enough to read off.

    I run a Minecraft server off 2GB of RAM with 3 or 4 people its fine. If you can answer these questions I would be able to assist more. Also dual core is more plenty its just the RAM you are struggling with.
