hi,章大侠
发现一个bug，不知道是nginx还是nginx-lua模块的
现象是: 当我们使用ngx.location.capture到一个m3u8文件(缓存命中的情况)
，打印出res.header.content_length 是正常的，大概948，而res.body的大小是523933
， body里面前面948字节是正常的，后面全是乱码
2015/03/28 17:31:59 F[ngx_http_lua_log.c] L[248] f[log_wrapper]
[error] 2280#0: *7088 [lua] channel_upstream_hls_handler.lua:122: modifyResponseAndReturn():
res.header.content_length not equal
res.body size , m3u8 length = 523933 res.header.length:948,
client: 133.1.7.5, server: chenw_cdn_cache, request: "GET /xxxxx/xxxx/filename.m3u8?IASHttpSessionId=xxx&livemode=1
HTTP/1.1", host: "133.1.7.4:6060"
而且，当我们pkill -9 nginx的时候 ，过段时间，比较容易出现上述情况。
没有进行pkill -9 nginx的操作，好像很久也不会出现。
目前我们对这个进行了异常防护，不相等就不处理。
不过想问下，章大侠遇到过吗，是不是个已知的bug？
谢谢
