fluidsGL example from CUDA SDK not working

I am running the fluids GL example from CUDA SDK 4.0 on a server with 4 tesla c2070 cards (RedHat Linux 4) and I see this error:

$ ./fluidsGL 

[fluidsGL] starting...

[fluidsGL] - [OpenGL/CUDA simulation] starting...

   OpenGL device is Available

X Error of failed request:  BadRequest (invalid request code or no such operation)

  Major opcode of failed request:  145 (NV-GLX)

  Minor opcode of failed request:  39 ()

  Serial number of failed request:  28

  Current serial number in output stream:  28

I have installed freeglut-2.8.0 and I am not sure why this error occurs?? ANy suggestions?

Thanks in advance.
