"Could not reserve enough space"

Hey guys,

I started reinstalling a craftbukkit server on my new PC, which has 16GB of RAM, but I'm still not able to give the server more than 1024MB of RAM.
No matter how much RAM I enter it keeps telling me "Could not reserve enough space".
How do I give the server more RAM?


Thanks for your help!

I now managed to give the server more RAM by installing the 64bit-Version of Java.
However now everytime I launch the server I get the warning:

Code:

>WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by io.netty.util.internal.ReflectionUtil (file:/C:/Users/maxgl/Desktop/Minecraft/Server/craftbukkit.jar) to constructor java.nio.DirectByteBuffer(long,int)
WARNING: Please consider reporting this to the maintainers of io.netty.util.internal.ReflectionUtil
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

What does this mean and how to fix this error/warning?

From what I can tell, the error message should not interfere with any other part of spigot. The reason this is happening is because Java 9 is not fully supported. To remove the error message, downgrade to Java 8.

 

Thank you for the information. As long as the server is running fine I will keep Java 9.
