Subject: nginx reverse proxy getting ECONNRESET
Date: Tue, 24 Mar 2015 22:43:40 +0000
Message-ID: <CABHxtY7Sn5yaiR5a3gDk1G4XySE+UtfuqUTcOSdmwneXLD5rcg@mail.gmail.com> (raw)

We have an nginx 1.6.2 proxy in front of a Unicorn 4.8.3 server that
is frequently reporting the following error:

2015/03/24 01:46:01 [error] 11217#0: *872231 readv() failed (104:
Connection reset by peer) while reading upstream

The interesting things are:

1) The upstream is a Unix domain socket (to which Unicorn is bound)
2) Unicorn isn't reporting that a child died in the error log (and I
verified their lifetimes with ps(1))

Any hints as to what we should look for?

Thanks,

--Michael
