Android emulator failed to allocate memory 8

When I try to run my WXGA800 emulator from Eclipse it's giving an error like this

Failed to allocate memory: 8
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

I checked the following links also

I have tried reducing RAM size in emulator and increasing Java heapsize and ramsize but still I am facing the same error.
