    I am hosted on a VPS with:
    Memory: 3gb
    Burst: 3gb
    OS: Cent OS 5 32 bit
    Java Version:
    I am receiving an error when I start bukkit. I have properly installed java. And I am in the correct directories.

    Code:
     java -Xms512m -Xmx2600m -jar craftbukkit.jar nogui
    After doing that command I get the following:

    Do notice the line in the above quote ""sh": java.io.IOException: error=12, Cannot allocate memory."

    The server will generate a world, but you can not connect to it using the MC client. Does anyone know what the problem is?


    Thank you for your help.

    I assume it is 32 bit. When I type "java -version" it doesn't say 64 bit or anything.

    Using OpenJDK? VPS's with burst memory (OpenVZ) don't have swap, and OpenJDK hates minecraft without swap.
    You should try Sun Java 6 using the repositories if your not using it.
    Had the same issue with OpenJDK in my VPS (when I had it) and when I switched to Sun Java 6, everything was fixed.

    You'd have to google for sun java repositories, I have no idea what it is anymore as its been months since I fixed it.

    32 bit can only use up to 1.5 gb ram!

  9. Wanted to post my findings.. it is because VPS don't get ANY swap space.. I get the same error unless i run "java -Xms256 -Xmx256 -jar craftbukkit.jar nogui"

    I submitted a support ticket for this issue because my server runs and I can have players. Though my issue is that when I use the reload command... Everyone gets disconnected and takes 8 seconds to reload. vs using the same config on my windows desktop I have no issues at all. Also on my centos box it takes 0.78seconds to load everything vs my home desktop is only 0.2 for initial script loading.
