Please help!

 

Am I sure it's because of not enough memory?
Try give more RAM in command line in server start script.

 

The server is running on 10GB of RAM. It should definitely have enough memory? I can try upgrading to 12GB.

 

There should be more of the error , could you post it here plz

 

I believe this is the entire error shown in the Console:

/home/multicraft/servers/server4538/./crash-reports/crash-2013-04-07_19.32.43-server.txt would probably help anyone who might be looking at this topic.

 

Try using craftbukkit without any plugins and c if the problem still exisits

 

I saw that error before, and I had to delete the player.dat file to circumvent it. Somehow the player.dat file got corrupted.
Check if it happens every time when player bziir logs on ...
