无法启动 Glassfish 3.1：java.io.IOException：error=12，无法分配内存

Question

我刚刚从 A2Hosting 购买了 ubuntu 9.0.4 VPS（256 MB 专用 RAM（512 MB Burstable）），并尝试在其上安装 Glassfish 服务器。当我尝试 asadmin start-domain 时，出现此错误

JVM failed to start: java.io.IOException: Cannot run program "/usr/local/jdk1.6.0_22/bin/java" 
(in directory "/home/harry/glassfish3/glassfish/domains/domain1/config"):
java.io.IOException: error=12, Cannot allocate memory
Command start-domain failed.

这是 free 命令的结果。

             total       used       free     shared    buffers     cached  
Mem:        524288     148552     375736          0          0          0

编辑 包含 domain.xml

尝试减少 -Xmx512m 行中的数量，直到获得有效的结果。然后联系您的提供商并了解您的限制在哪里。
