刚遇到奇怪的问题.当我打字

java -version

我有

Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

.

java -Xms64m -Xmx64m -version

这个命令工作正常

java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07)
Java HotSpot(TM) Client VM (build 19.1-b02, mixed mode)

如果我将xms,xmx更改为128m,我会再次收到错误.

使用top命令,free -m我可以看到,我有超过192 MB的免费,所以为什么我仍然得到这个错误？

Mem:    262144k total,    64760k used,   197384k free,        0k buffers
Swap:        0k total,        0k used,        0k free,        0k cached

谢谢
