android - OpenGL ES 2.0 spamming log with 'unable to find phys addr ...' -

i using fragment shader

// pixel shader gouraud shading - per-vertex lighting  precision mediump float;  // texture variables uniform sampler2d texture1; // color texture  varying float tex; varying vec2 tcoord;  // color varying vec4 color;  void main() {     if(tex==0.0)     gl_fragcolor=color;     else {     gl_fragcolor=texture2d(texture1, tcoord);     } } 

everything works fine textured models. if render models without textures, log spammed following line every frame

unable find phys addr 204b70

when comment out else part in fs, there no error logs. checked value of tex in fs color method , 0.0. suggestion?
