Hello. We have some strange issues when requests seems to stall inside nginx - in nginx log we see that request took 1 second (and was terminated by client timeout), while excactly the same request (we have special unique headers to mark them) from the uwsgi logs took only 100ms to complete.
We also saw some very strange pauses in nginx debug log: 2017/01/26 20:17:51 [debug] 2749#0: *75780960 get rr peer, try: 2 2017/01/26 20:17:51 [debug] 2749#0: *75780960 get rr peer, current: 00007F6EC6C3D1F0 -1 2017/01/26 20:17:51 [debug] 2749#0: *75780960 stream socket 500 2017/01/26 20:17:51 [debug] 2749#0: *75780960 epoll add connection: fd:500 ev:80002005 2017/01/26 20:17:51 [debug] 2749#0: *75780960 connect to 10.0.0.176:80, fd:500 #75780961 2017/01/26 20:17:51 [debug] 2749#0: *75780960 http upstream connect: -2 2017/01/26 20:17:51 [debug] 2749#0: *75780960 posix_memalign: 00007F6EC5213D60:128 @16 2017/01/26 20:17:51 [debug] 2749#0: *75780960 event timer add: 500: 10000:1485451081089 2017/01/26 20:17:51 [debug] 2749#0: *75780960 http finalize request: -4, "/api/info/account/type/278933/?" a:1, c:2 2017/01/26 20:17:51 [debug] 2749#0: *75780960 http request count:2 blk:0 2017/01/26 20:17:51 [debug] 2749#0: *75780960 http run request: "/api/info/account/type/278933/?" 2017/01/26 20:17:51 [debug] 2749#0: *75780960 http upstream check client, write event:1, "/api/info/account/type/278933/" 2017/01/26 20:17:51 [debug] 2749#0: *75780960 http upstream recv(): -1 (11: Resource temporarily unavailable) 2017/01/26 20:17:54 [debug] 2749#0: *75780960 http upstream request: "/api/info/account/type/278933/?" 2017/01/26 20:17:54 [debug] 2749#0: *75780960 http upstream send request handler 2017/01/26 20:17:54 [debug] 2749#0: *75780960 http upstream send request 2017/01/26 20:17:54 [debug] 2749#0: *75780960 http upstream send request body 2017/01/26 20:17:54 [debug] 2749#0: *75780960 chain writer buf fl:1 s:433 2017/01/26 20:17:54 [debug] 2749#0: *75780960 chain writer in: 00007F6E975088B0 2017/01/26 20:17:54 [debug] 2749#0: *75780960 writev: 433 of 433 2017/01/26 20:17:54 [debug] 2749#0: *75780960 chain writer out: 0000000000000000 2017/01/26 20:17:54 [debug] 2749#0: *75780960 event timer del: 500: 1485451081089 2017/01/26 20:17:54 [debug] 2749#0: *75780960 event timer add: 500: 200000:1485451274089 2017/01/26 20:17:54 [debug] 2749#0: *75780960 http upstream request: "/api/info/account/type/278933/?" 2017/01/26 20:17:54 [debug] 2749#0: *75780960 http upstream process header 2017/01/26 20:17:54 [debug] 2749#0: *75780960 malloc: 00007F6E97AC0070:4096 2017/01/26 20:17:54 [debug] 2749#0: *75780960 posix_memalign: 00007F6ECACC95D0:4096 @16 2017/01/26 20:17:54 [debug] 2749#0: *75780960 recv: fd:500 408 of 4096 2017/01/26 20:17:54 [debug] 2749#0: *75780960 http proxy status 200 "200 OK" Any help would be appreciated.
