Mac Server Crash Error

[Jeza]

I was trying to setup a server using the Direwolf20 Map. I downloaded the client files and ran the server through the .jar file as it was the only one that worked. This would eventually crash giving me the following:

[INFO] Starting minecraft server version 1.4.6
[WARNING] To start the server with more ram, launch it as "java -Xmx1024M -Xms1024M -jar minecraft_server.jar"

...(I shortened this because the post would be huge)...

Sorry if I did not post this in the right format it is my first time in this forum.
Thank you for any help, it would be much appreciated!

Have you tried increasing the amount of RAM in your startup script? It's an OutOfMemoryError, but I don't know if this is caused by something else.

Please post your java version also.

cd ~(replace with link to file) ex: /uses/username/desktop/ftb
java -Xincgc -Xmx1024M -jar minecraft_server.jar

save this as a .command file after you edit the cd~ part. then use this to launch the server
