Hi, I found following bug in nginx-1.8.0:
if aio is configured with threads support - sometime (one in thousands requests) $bytes_sent contains only length of the header. I'm attaching my nginx.conf, build params and simple python script I'm using the reproduce this issue. Here is the output of test script when the problem appears: . . . received: 101700000 from access_log : 101700000 on 26 iteration 127.0.0.1 - - [15/May/2015 17:27:45] "GET /test HTTP/1.0" 200 - 127.0.0.1 - - [15/May/2015 17:27:47] "GET /test HTTP/1.0" 200 - received: 101700000 from access_log : 101700000 on 27 iteration 127.0.0.1 - - [15/May/2015 17:27:58] "GET /test HTTP/1.0" 200 - 127.0.0.1 - - [15/May/2015 17:28:00] "GET /test HTTP/1.0" 200 - received: 101700000 from access_log : 101690000 on 28 iteration test failed!! also in access_log file" . . . 10170 GET /test HTTP/1.1 10170 GET /test HTTP/1.1 10170 GET /test HTTP/1.1 170 GET /test HTTP/1.1 10170 GET /test HTTP/1.1 10170 GET /test HTTP/1.1 . .
