Hi, I'm not familiar with the bucket, brigade at all. It seems that the chunk will be sent via bucket brigade. I found the stuck happen when the length of the bucket is "0" and the next length of the bucket is "5" (0\r\n\r\n, is this the last chunk?).
Why isn't the last chunk inserted in the bucket with web data? Why the last two buckets with zero and five length aren't sent out?
