Hi all, 

    i am writing opengles program for android platform that read from own framebuffer after rendering into it , and i arrange two thread which one to render, the other to read. besides, in order to read the correct rendered buffer data, i will insert an fence after calling glDrawArrays, and waiting the fence before reading buffer. unfortunately, sometimes will got the warning message, which is :

 
04-11 20:48:46.063 17443 17551 W Adreno-GSL: <gsl_ldd_control:466>: ioctl fd 35 code 0x400c0907 (IOCTL_KGSL_DEVICE_WAITTIMESTAMP_CTXTID) failed: errno 110 Connection timed out
