Hello. To me, it looks rather a random failure. Is it actually reproducible
and proven that the patch has caused it? The patch doesn't seem to cause
the fails below.
Cheers,
Michael

thanks for the input, we will look into this and provide update. Now since
we are in Chinese national holiday (until Oct 9), please allow some time
before we get back to work on this.
Thanks
