EGL_emulation failed to establish connection to host - android

Question

I am trying to run a simple OpenGL program in Android. I am running this in an Android 4.1 emulator. I switched on its GPU emulation and it worked fine yesterday. When I ran that today, initially it was hanging saying, OpenGL taking time to render - Wait or Close dialog box. After few runs again it was crashing saying

E/EGL_emulation(2637): Failed to establish connection with the host

I guess the emulator is not able to take control of the GPU of the system, so how do I avoid this error? How do I rectify this problem?

Thanks in advance. :)

This happens to me when my computer came out standby. Restart your virtual device.
