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

I got this java problem

[root@peach sbin]# java
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
[root@peach sbin]# free -m
             total       used       free     shared    buffers     cached

This is a virtual machine. I am thinking this pr开发者_如何学Pythonoblem because of the memory is not big enough. If some one agree with me.

It is running with a CentOS release 5.6 (Final)

Thanks

Try

java -Xmx64m

Basically your machine doesn't have enough memory, but you may be able to get away with 64MB. Let me know how you get on.

You can use this command to know your current memory usage:

swapinfo -tam

I had the same error and the memory use was above 95%.
