*1472988 lua socket connect timed out, client: 172.16.8.10, server: dbtest1,
request: "GET /test1 HTTP/1.1", host: "192.168.13.63"
redis使用的sample代码的set/get部分，新建连接后尝试red:set_keepalive(0, 100)或者red:close()，两种情况下均会出现上述报错。
nginx使用的tengine 1.3.0, luagit是最新版本(stable版本不支持64bit?). 连接数在大约4000左右就达到了瓶颈， 3000左右就开始出现大量的socket connect time out错误。所有请求都返回了200.
