Hello,
Recently I noticed log lines with a status code of -1, not sure how long this has been going on for however so not sure if it is a new issue or an older one. In our environment we set strict timeouts as requests (once we get them) need to be processed in < 80ms. A cleaned up version of the config is located here: http://pastebin.com/FK3KG1Gi They always happen with a backend server connect timeout, but I also see 503 responded for the same type of timeout. Logs (custom log format removed): Nov 12 21:07:53 haproxy[13800]: x.x.x.x:xx [12/Nov/2014:21:07:53.646] incoming bproxy-client1/server1 0/0/-1/-1/4 503 27 - - sC-- 2046/2046/3/1/0 0/0 "POST /url/here HTTP/1.1" Nov 12 21:07:53 haproxy[13800]: x.x.x.x:xx [12/Nov/2014:21:07:53.608] incoming bproxy-client1/server1 38/0/-1/-1/43 -1 0 - - sC-- 2047/2047/2/1/0 0/0 "POST /url/here HTTP/1.1” I know the default status of each txn is set to -1, so I’m not sure if this is bailing out along the line. This issue is reproducible on 1.5.{dev24, 4, 8} I am working on reproducing this outside of production. Thanks! Tait
